Telling Tramp NOT to use authinfo.gpg

Telling Tramp NOT to use authinfo.gpg

[Gleb Nemshilov]

I use authinfo.gpg file for storing passwrods for Gnus only. This causes Tramp to constantly ask password for .authinfo.gpg.

Is it possible to disable this behaviour?

I tried setting "tramp-completion-use-auth-sources" to nil, but that does not help and I still get prompted for the password each time I use Tramp with something like "/su::/" and pressing Tab.

When nil, this user option disables to use your .authinfo.pgp when
completing host names. So you shall keep it nil.

Disabling .authinfo.gpg for Tramp is not foreseen. The most simple
workaround is to eval after loading tramp.el

(fset #'tramp-read-passwd
      (lambda (key &optional prompt)
	(password-read (or prompt "Password: ") key)))

Hi Michael!

Thank you, it works perfectly!

However it changes the prompt message and I understand why it happens. The original function has a lot of code, and I couldn't find which part is responsible for the prompt message. Is it possible to get similar behaviour and see the name of the user/host for which I enter the password?

In that case, it might be better if you use connection-local variables
in order to disable auth-sources for Tramp. Something like this:

--8<---------------cut here---------------start------------->8---
(connection-local-set-profile-variables
 'remote-without-auth-sources '((auth-sources . nil)))

(connection-local-set-profiles
 '(:application tramp) 'remote-without-auth-sources)
--8<---------------cut here---------------end--------------->8---

It seems to work with Emacs 27.1, but not in all cases. You might try
it.

I've applied a patch to Tramp to let it work robustly, for all
backends. Available with Tramp 2.5.0, which is scheduled for end of this
year via GNU ELPA.
