Hi,
I have been trying out using oauth2.el to enable OAuth2-based
authentication for email service providers and had some success for
Gmail. During this process, I have made a few changes to oauth2.el that
enables it to use with Gmail OAuth2 as well as some usability and
debugging improvements, which I'm sharing below.
This is a series of five patches, which are attached.
The first patch shows the authentication URL in the minibuffer window
alongside the prompt accepting the authorization code. This helps when
a user has multiple accounts from the same provider but is logged into a
different account than the one that the user is trying to set up. If
the user use the link (or through `browse-url') it will use the active
account instead of the one intended. By showing the URL in the
minibuffer, the user can choose other ways to get the authorization code
(e.g. using another browser, using private/encognito mode, etc.)
The second patch adds the parameters `access_type=offline' and
`prompt=consent' to the authorization URL, which is required for Gmail
OAuth2 to get the refresh token. Without these 2 parameters, Gmail
response will only contain the access token which expires in one hour.
They should also be compatible with other OAuth2 authentication process.
(Though I am currently having trouble to get outlook.com to work
regardless of these parameters, which I'll ask in a separate thread.)
Note that the second patch depends on the first patch as they modify the same
part of the code.
The third patch encodes the parameters for requesting refreshing access
token, which is recommended because the client secret and other
parameters may contain characters that may break parameter parsing.
The fourth patch may need a bit of background: oauth2.el (optionally)
uses plstore to save authentication data for future reuse, and the
plstore id for an account is computed using a combination of `auth-url',
`token-url', and `scope'. However, this combination of data doesn't
guarantee uniqueness for accounts for a same provider, e.g. for Gmail,
the three parameters are the same for different accounts, and hence
storing a second account information will override the first one.
This fourth patch adds `client-id' to the calculation of plstore id to
ensure its uniqueness. This may cause a few concerns:
- This will invalidate all existing entries and a user will have to redo
the authorization process again to get a new refresh token. However,
I think it's more important to ensure that oauth2.el works correctly
for multiple accounts of the same provider, or a user may suffer from
confusion when adding a new account invalidates a previous account.
- Adding `client-id' to the calculation of plstore id may provoke
suspicion of leaking it as the hash calculation uses md5. In most
cases, requesting a refresh token requires both `client-id' and
`client-secret', so without including the latter it should be safe.
There are cases when requesting only the access token may work with
`client-id' along. Still, I think this should not be a big concern as
the data is combined with `auth-url', `token-url', and `scope' which
provides sufficient salt. Alternatively, we can also choose to use a
more secure hash function, e.g. SHA2 or better, given that existing
entries will be invalidated anyway.
The fifth patch adds debug messages when doing a URL query which records
the request URL, the request data, and the response data, and provide a
custom variable to enable this. This provides a way to help debugging
the requests, and I find it handy when testing oauth2 against different
providers.
Please review and comment. TIA!

Subject: [PATCH 4/5] Support storing data for multiple accounts of the same
provider
Currently the plstore id computed by `oauth2-compute-id' only takes
`auth-url', `token-url', and `scope' into account, which could be the
same for the same provider (e.g. Gmail). This prevents storing
information for multiple accounts of the same service for some
providers.
This patch adds `client-id' to the calculation of plstore id to make
sure that it is unique for different accounts of the same provider.
* packages/oauth2/oauth2.el (oauth2-compute-id): add `client-id' as a
parameter of `oauth2-compute-id' to ensure unique id amount multiple
accounts of the same provider.

Thank you for this. This support is becoming more necessary as time
goes on. I even wonder if we should bring oauth2.el into emacs instead
of it being a package.

OK. This fixes one of my irritations with oauth2.el 🙂
Xiyue> The second patch adds the parameters `access_type=offline' and
Xiyue> `prompt=consent' to the authorization URL, which is required for Gmail
Xiyue> OAuth2 to get the refresh token. Without these 2 parameters, Gmail

Xiyue> They should also be compatible with other OAuth2 authentication process.
Xiyue> (Though I am currently having trouble to get outlook.com to work
Xiyue> regardless of these parameters, which I'll ask in a separate thread.)
Xiyue> Note that the second patch depends on the first patch as they modify the same
Xiyue> part of the code.
OK. Iʼm assuming oauth2.el can use the refresh token next time it
needs to authorize? (Iʼve been avoiding actually using oauth2.el in
anger, since app passwords still work)
Xiyue> The third patch encodes the parameters for requesting refreshing access
Xiyue> token, which is recommended because the client secret and other
Xiyue> parameters may contain characters that may break parameter parsing.
OK
Xiyue> The fourth patch may need a bit of background: oauth2.el (optionally)

Xiyue> plstore id for an account is computed using a combination of `auth-url',

Xiyue> guarantee uniqueness for accounts for a same provider, e.g. for Gmail,
Xiyue> the three parameters are the same for different accounts, and hence

Xiyue> This fourth patch adds `client-id' to the calculation of plstore id to

Xiyue> - This will invalidate all existing entries and a user will have to redo

I donʼt think thatʼs too big a concern. 'modern' authentication flows
regularly re-prompt, so this will not be too surprising (although
maybe call it out in the packageʼs NEWS or README).
Xiyue> - Adding `client-id' to the calculation of plstore id may provoke
Xiyue> suspicion of leaking it as the hash calculation uses md5. In most
Xiyue> cases, requesting a refresh token requires both `client-id' and
Xiyue> `client-secret', so without including the latter it should be safe.
Xiyue> There are cases when requesting only the access token may work with
Xiyue> `client-id' along. Still, I think this should not be a big concern as
Xiyue> the data is combined with `auth-url', `token-url', and `scope' which
Xiyue> provides sufficient salt. Alternatively, we can also choose to use a
Xiyue> more secure hash function, e.g. SHA2 or better, given that existing
Xiyue> entries will be invalidated anyway.
If the existing entries are going to become invalid anyway, you might
as well take the opportunity to move away from md5 at the same
time. git picked SHA-256, but that was a while ago, so maybe SHA-512?
Xiyue> The fifth patch adds debug messages when doing a URL query which records
Xiyue> the request URL, the request data, and the response data, and provide a
Xiyue> custom variable to enable this. This provides a way to help debugging
Xiyue> the requests, and I find it handy when testing oauth2 against different
Xiyue> providers.
OK (although perhaps make it a defvar rather than a defcustom, to
avoid people accidentally enabling it).

In many cases the refreshing of tokens is transparent to the user there
doesn't have to be a re-prompt to refresh the token if the OAuth
provider support it.
Micrsofts OAuth workflow is quite good in this regard as there's a
non-standard error to indicate when the user has to re-authorize the
application.
I assume all implementation of OAuth have their quirks.

Would it make sense to plug OAuth2.el into auth-source to store the
authentication token safely inside an existing credential storage?
Various applications already do so when using the native credential
storages such as Freedesktop.org or the macOS keyring.

Yes. In fact thereʼs the auth-source-xoauth2 package that does
that. And oauth2 can already store stuff using plstore, so Iʼm sure it
can be extended to use auth-source.

I would also love that to happen. In fact, I have another addon
inspired by auth-source-xoauth2 and makes use of oauth2.el and
auth-source backend, though it requires advising the
auth-source-search-backends and kind of awkward. I'll post that through
another bug report for comments after this one gets submitted.

Yes, with a valid refresh token you can login without any manual steps.
Unless the refresh_token itself is expired, in which case you'll have to
re-authorize.

I have added a NEWS file in patch 6 documenting this for 0.17 (which
should be the version of the next release.)

Makes sense. I have updated the hash function to use SHA-512 in patch 5.

Subject: [PATCH 4/6] Support storing data for multiple accounts of the same
provider
Currently the plstore id computed by `oauth2-compute-id' only takes
`auth-url', `token-url', and `scope' into account, which could be the
same for the same provider (e.g. Gmail). This prevents storing
information for multiple accounts of the same service for some
providers.
This patch adds `client-id' to the calculation of plstore id to make
sure that it is unique for different accounts of the same provider.
It also changes the hash function to sha512 to be more secure.
* packages/oauth2/oauth2.el (oauth2-compute-id): add `client-id' as a
parameter of `oauth2-compute-id' to ensure unique id amount multiple
accounts of the same provider, and change hash function to sha512.

+Summary of changes to oauth2.el
+-------------------------------
+
+For changes of 0.16 and older or full changes please check the git
+history of the repository of oauth2.el.
+
+* 0.17
+
+** Changes to plstore id generation and needs to reacquire refresh_token
+
+The generation of plstore id used to include `auth-url', `token-url',
+and `scope'. Now `client-id' is also included. This is required to
+support multiple accounts of some providers which use the same
+`auth-url', `token-url', and `scope' (e.g. Gmail), and hence the
+generated plstore id is not unique amount accounts. Adding
+`client-id' solves this problem.
+
+The hash function of calculating the plstore id has also changed from
+MD5 to SHA512 to be more secure.
+
+As a result, users of oauth2.el will need to redo the authentication
+process to get a new refresh_token when upgrading from older version
+to 0.17.

Actually I am currently having trouble for a few weeks to get my
outlook.com email work with MS OAuth2. To avoid some repeated typing, I
have documented the issues and steps I have tried in this stackoverflow
question[1]. I would great appreciated it if you can shed some lights
there

As I mentioned to Robert, I do have another addon to do exactly this,
though through an awkward advice. Would be great if auth-source can
make use of oauth2.el and handle that more gracefully. I'll file
another bug to explore options once this one is done.

auth-source-xoauth2 doesn't actually use auth-source
(e.g. ~/.authinfo.gpg) to store the data it needs, but use a custom file
storing an ELisp hash table to store the client-id, client-secret, etc.
It does advice the authentication code to use the calculated token.

I remember when adding OAuth support to Sailfish OS we needed to patch
our signon to work with the non-standard Microsoft flow.
We have this patch on top of the OAuth2 plugin for signond to accept
that they send the authentication as a request for you to fetch upon you
have to another request with the new url to get authentication code.
The patch can be found here:
https://github.com/sailfishos/signon-plugin-oauth2/blob/master/rpm/0005-Support-Microsoft-OAuth2-flow.patch
I'm not the person who wrote the patch but I fixed the plugin later for
Dropbox so that PKCE (RFC7636) isn't used unless the server requests it
(response type must be code to request PKCE).
PKCE is strongly recommended. The patch above already works kinda that
way without requesting PKCE.

Care to post this advice? It's not an optimal solution but better than
nothing in the interim.

It currently depends on this modified oauth2.el. Once the patches are
accepted I'll post it in a separate bug.

I see you changed `oauth2-token-file' to a `defvar', which I donʼt
think you should do. I was talking about making `oauth2-debug' a
defvar.

[-- Attachment #1: Type: text/plain, Size: 1166 bytes --]
I have been using the existing oauth2.el and auth-source.el to use both
gmail and outlook (through my university) with oauth2 for several years
now (I posted a bit about it some time ago on the devel list). I
didn't need to change much to get it to work so I thought as long as the
changes by Xiyue are being considered (all of which look good to me) I
would chime in. I'm happy to provide more info about my setup and usage
if anyone is interested.
Firstly, I note that I have gmail working fine without the change in
patchset 2 (although I see nothing wrong with the change, I wonder why
it isn't necessary for me but is for Xiyue).
Secondly, there is one other important change that I have been using
which should probably be added to oauth2.el (I communicated the change
to Julien a long time ago, but he said he is no longer actively
maintaining oauth2.el): in refreshing the token the access-response is
ignored (as is the response-error). The access-response contains
information about the token expiration so its needed in order to control
when to fetch a new token. The simple patch below stores the
access-response in the appropriate slot in the token:

[-- Attachment #3: Type: text/plain, Size: 2542 bytes --]
Lastly, a brief description of how to get things to work with
auth-source and existing code (subject to the change I mentioned above):
auth-source entries using the plstore backend allow the secret to be a
function (which is passed the whole entry plist as an argument). All
that is needed then is a function that returns the access token (which
is then used in gnus and smtpmail, both of which already work properly
with an oauth2 access-token). A simple function to check the expiration
time and fetch a new access-token if necessary (and update the new token
and expiration information) and then return the access-token is what I
use.
So I used auth-source to create plstore entries for gmail and
outlook containing the oauth2 tokens, and set the secret to the
following function
(defun gnus-refresh-access (plist)
"Return an oauth2 access-token for PLIST.
If the current token has expired, fetch, save, and return a new one."
(cl-destructuring-bind
(&key user host port token last-update
(expires_in (alist-get 'expires_in
(oauth2-token-access-response token)))
(create-args
(list :type 'plstore :create
'(:encrypted (token client-secret-sav)
:unencrypted (auth-url scope redirect-uri last-update smtp-auth))))
&allow-other-keys) plist
(unless (and (numberp expires_in) (numberp last-update)
(< (float-time) (+ last-update expires_in)))
(message "Getting new token for %s at %s:%s" user host port)
(setq plist (plist-put plist :secret 'gnus-refresh-access))
(setq plist (plist-put plist :last-update (truncate (float-time))))
;; get a new token and update the plist
(setq plist (plist-put plist :token (oauth2-refresh-access token)))
;; update auth-source---if something in the plist has changed
;; then no entry will be found during the search, and the
;; create flag will be honored.
(apply #'auth-source-search (append plist create-args)))
;; return the access token
(oauth2-token-access-token (plist-get plist :token))))
By the way, I let auth-source handle the plstore rather than
oauth2.el. It seemed simpler to have only one of them managing the store
rather than both.
By the by the way, there are some important bugs in auth-source.el that
I have fixed in my personal tree (and a few that I haven't). I'll post
about them in a separate bug report at some point.
Best,
Andy

I have not seen it mentioned in this thread yet, so here goes: my
url-http-oauth package in GNU ELPA supports storing credentials in
~/.authinfo.gpg and refreshing them. It would be nice if your OAuth2
work could get feature parity with it, then I could delete my package;
feel free to copy any code that makes sense. (I do not use
url-http-oauth anymore, but I felt the need to write it when I was using
Excorporate and OAuth.)
Ideally you could get the result (and the xoauth2 support for IMAP and
SMTP) accepted in Emacs core.
(Then, extremely ideally, the FSF could work out legal agreements with
the various OAuth providers to get Emacs registered as an OAuth
application, like, e.g., Thunderbird.)

Thanks for working on url-http-oauth! I think it adds credential
management using auth-source, e.g. prompt for client-id and
client-secret and store them, which my other addon (that I'll post next
as it depends on the changes I made here) didn't do. Ideally this
should be handled transparently by all auth-source backends and say Gnus
when you add a new account, but IIUC currently the JSON backend doesn't
support creation, which I'm using for ease to read and modify.

That would be great! My other addon uses advice, but it would
definitely be better to be integrated in core (which already has partial
support)

That would be the best for the end user. Imagine a Gnus user could just
add a new account and on launch Gnus the default browser will open the
login page (or be prompted an URL to visit), which then normally handles
all the login shenanigans (2FA, authenticator, etc.) and viola, you're

More reviews welcome!
BTW, is there any dev available to commit the changes once it's in a
good shape?

You could request commit access. I see you have a number of
contributions to Emacs already.

I think depending on the authentication storage it would make sense to
provide a custom setting with a sane default that allows the user to
configure a path inside the storage to store their credentials.
These could then have templates for the hostname, user, port etc just
like the regular search parameters that `auth-sources-search' supports.

From Gnus point of view I think it would make it easier to support
auth-source as then Oauth support would come for free as then the
credentials can be retrieved just for basic authentication.
Some kind of hook or trigger to call renewal functions would be needed
though so that tokens can be refreshed transparently or manually if the
user needs to re-authenticate.

To allow seamless authentication the FSF could make things much smoother
by registering Emacs with common providers, working with FSFE together
in this regard could help too (there are other countries than the U.S.).
The issue I see is that registering Emacs is not enough since Emacs is
in this context merely a runtime for these modes that want to use OAuth.
The scope of the permissions they need varies, so their names etc.

That would be great to have. Do you know how I can apply for it (I have
already done the paperwork)?

Just want to report back that after confirming with an MS representative
through online chat, outlook.com has actually disabled refreshing
access_token through the token endpoint, and users are asked to migrate
to Outlook app or compatibles apps (Thunderbird still works). I'm not
sure whether this is also the case for organization emails, which may
also be disabled by default (or soonish if not already) but can be
enabled separately by an org admin. Anyway, I'd suggest people stop
wasting your time here and use Gmail (or maybe Yahoo mail) which has
decent 3rd party OAuth2 support.
Meanwhile I have submitted a request to re-enable this support[1].

It does depend some domains use whitelist e.g. Tampere University of
Applies sciences. Without a specific Emacs GNUs/Caldav/whatever AppID
inside Microsoft OAuth2 it will be hard to pass that.

I don't think that's an option for most user that complain about working
OAuth2 support, in most cases it's a work or some other organization
account.
Another thing I think is very important is to support Nextcloud as it's
a FOSS app supporting OAuth2 which quite many users and organizations
adopted.

Nextcloud sounds interesting. Do you know where I can check for the

You can find them in the administrator settings the Nextcloud server.
Here is there documentation:

OK that is to bad, if possible I would ask for an official
response. Microsoft counts as a gate keeper, at least officially in the
EU, they should not be able to act like this.
A workaround would be to request a manual token refresh by authorizing
the application all over again.
I will update you on anything new I have if I get new information that I
can post.

sourcehut [1] provides a Free Software OAuth2 flow, and it has the
benefit of not requiring JavaScript (even FOSS JavaScript) anywhere in
the process. I wrote url-http-oauth-demo.el [2] as a complete "worked"
example demonstrating its use with url-http-oauth.el.

Would that provide OAuth2 for providers that require a login through
their webinterface, such as Nextcloud Login, without a browser?
Most platforms such as Android, KDE or Sailfish OS use a browser for
OAuth2 login to login, authorize and then forward the token to the
OS/app.

It's been a few days since the last time I received feedback for
improvements regarding my patches. Is there any other feedbacks/reviews
I am expecting from the co-maintainers? Please also let me know when
it's time to ask for merging and requesting a new tagged release.
Thanks in advance.

?? The last message in this discussion was just yesterday evening, and
my understanding is that you are still discussing the issues and did
not reach the final conclusion. If I'm mistaken, my apologies; please
describe your conclusion and post the patch that you-all agree would
solve the issues, and let's take it from there.

The recent communication was not related to my patches but to check
whether it is possible to support outlook.com OAuth2 login (and the
conclusion was no because refreshing access token was disabled as
confirmed by MS representative during an online chat.)

I actually only received comments from Robert and I have updated my

Sorry I accidentally hit sent for my previous mail (which actually ended
on a full sentence, what are the chances?)
To continue, the description of the patches is in the first message[3]
and not changed much except the added 6th patch which added a NEWS file.
TL;DR the patches include
* adding authorization request parameters required for Gmail OAuth2 to
work,
* updating key calculation in oauth2.plstore to include `client-id' so
that it can store multiple accounts for a given service, and
* usability and debugging improvements.
I haven't received more comments from Robert so I hope the patches now
look good to him. Still, I would like to invite for more reviews (if
any) and submit the patches when ready.
Thanks!

Subject: [PATCH 4/6] Support storing data for multiple accounts of the same
provider
Currently the plstore id computed by `oauth2-compute-id' only takes
`auth-url', `token-url', and `scope' into account, which could be the
same for the same provider (e.g. Gmail). This prevents storing
information for multiple accounts of the same service for some
providers.
This patch adds `client-id' to the calculation of plstore id to make
sure that it is unique for different accounts of the same provider.
It also changes the hash function to sha512 to be more secure.
* packages/oauth2/oauth2.el (oauth2-compute-id): add `client-id' as a
parameter of `oauth2-compute-id' to ensure unique id amount multiple
accounts of the same provider, and change hash function to sha512.

+Summary of changes to oauth2.el
+-------------------------------
+
+For changes of 0.16 and older or full changes please check the git
+history of the repository of oauth2.el.
+
+* 0.17
+
+** Changes to plstore id generation and needs to reacquire refresh_token
+
+The generation of plstore id used to include `auth-url', `token-url',
+and `scope'. Now `client-id' is also included. This is required to
+support multiple accounts of some providers which use the same
+`auth-url', `token-url', and `scope' (e.g. Gmail), and hence the
+generated plstore id is not unique amount accounts. Adding
+`client-id' solves this problem.
+
+The hash function of calculating the plstore id has also changed from
+MD5 to SHA512 to be more secure.
+
+As a result, users of oauth2.el will need to redo the authentication
+process to get a new refresh_token when upgrading from older version
+to 0.17.

Subject: [PATCH 4/6] Support storing data for multiple accounts of the same
provider
Currently the plstore id computed by `oauth2-compute-id' only takes
`auth-url', `token-url', and `scope' into account, which could be the
same for the same provider (e.g. Gmail). This prevents storing
information for multiple accounts of the same service for some
providers.
This patch adds `client-id' to the calculation of plstore id to make
sure that it is unique for different accounts of the same provider.
It also changes the hash function to sha512 to be more secure.
* packages/oauth2/oauth2.el (oauth2-compute-id): add `client-id' as a
parameter of `oauth2-compute-id' to ensure unique id amount multiple
accounts of the same provider, and change hash function to sha512.

+Summary of changes to oauth2.el
+-------------------------------
+
+For changes of 0.16 and older or full changes please check the git
+history of the repository of oauth2.el.
+
+* 0.17
+
+** Changes to plstore id generation and needs to reacquire refresh_token
+
+The generation of plstore id used to include `auth-url', `token-url',
+and `scope'. Now `client-id' is also included. This is required to
+support multiple accounts of some providers which use the same
+`auth-url', `token-url', and `scope' (e.g. Gmail), and hence the
+generated plstore id is not unique amount accounts. Adding
+`client-id' solves this problem.
+
+The hash function of calculating the plstore id has also changed from
+MD5 to SHA512 to be more secure.
+
+As a result, users of oauth2.el will need to redo the authentication
+process to get a new refresh_token when upgrading from older version
+to 0.17.

... and perhaps prefix the message with a string like "[oauth2] ".
I also notice that you manually mention the function issuing the debug
message below. It is possible to infer this using `backtrace-frame'
(but that is really something that should be added to the core, instead
of packages having to re-implement it themselves.)

Is pp-to-string here really much better than prin1-to-string? Note that
'oauth2--do-debug' is a function, so the arguments are always evaluated.
I have experienced pp being significantly slower than the core print
functions, so this is something that is worth thinking about IMO.

Perhaps you can add a file local variable to enable outline-mode?
All in all the patches look more than fine though, nothing I mentioned
is pressing. If you don't have the time and the changes are urgent,
then I can also apply them as such.

Because I asked him to make it a `defvar' :-) I donʼt think debug
options should be customizable, theyʼre not user-level.

Added a let-bounded `func-name' by getting function name from
backtrace-frame. And it would be great if there is a built-in macro
like `__PRETTY_FUNCTION__' and `__LINE__'.

It's just a personal preference. And it look like the values are mostly
key-value pairs so they are not that hard to read through
`prin1-to-string' so I changed to it.

Subject: [PATCH 4/6] Support storing data for multiple accounts of the same
provider
Currently the plstore id computed by "oauth2-compute-id" only takes
"auth-url", "token-url", and "scope" into account, which could be the
same for the same provider (e.g. Gmail). This prevents storing
information for multiple accounts of the same service for some
providers.
This patch adds "client-id" to the calculation of plstore id to make
sure that it is unique for different accounts of the same provider.
It also changes the hash function to sha512 to be more secure.
* packages/oauth2/oauth2.el (oauth2-compute-id): add "client-id" as a
parameter of "oauth2-compute-id" to ensure unique id amount multiple
accounts of the same provider, and change hash function to
sha512. (Bug#72358)

+Summary of changes to oauth2.el
+-------------------------------
+
+(For changes of 0.16 and older please check the git history of the
+repository of oauth2.el.)
+
+* 0.17
+
+** Changes to plstore id generation and needs to reacquire refresh_token
+
+The generation of plstore id used to include `auth-url', `token-url',
+and `scope'. Now `client-id' is also included. This is required to
+support multiple accounts of some providers which use the same
+`auth-url', `token-url', and `scope' (e.g. Gmail), or the generated
+plstore id is not unique amount accounts. Adding `client-id' solves
+this problem.
+
+The hash function of calculating the plstore id has also changed from
+MD5 to SHA512 to be more secure.
+
+As a result, users of oauth2.el will need to redo the authentication
+process to get a new refresh_token when upgrading from older version
+to 0.17.

No, some packages use user options, others regular variables so I guess
it is up to the person with the strongest opinion on the topic to decide
(which isn't me in this case).

Thanks a lot Philip! One last thing: I'd like to ask for a new release
(0.17) with these changes if that's OK (patch attached.) Or let me know
if I should create a new bug for that.

Of course, I forgot to ask if this should trigger a new release or not,
that's my bad.

Nah, not for something as simple as this. I'll apply it straight away.

In case anyone is interested, I have filed bug#72992[1] where I posted
my code to enable xoauth2 support for nnimap and smtpmail as I promised.
I am also trying to gather feedback on how it can be improved. Comments
welcome!
