Several months ago there was a request to have auth-source.el use the Mac OS X keychain functions (see http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00486.html). These functions are documented at http://developer.apple.com/library/mac/#documentation/Security/Conceptual/keychainServConcepts/03tasks/tasks.html. I agreed to do it but then got busy and later forgot about it. I want to finally keep my promise this weekend. When I started looking into what would be needed to complete this task the first thing I noticed is that auth-source.el makes use of the functions in secrets.el I mentioned if the user customizes the auth-sources variable to include the secrets API. Since the Keychain Services API provides functionality similar to that provided by the org.freedesktop.secrets interface I figured that secrets.el would be a logical place to put the change. Putting the code there also makes it available to packages other than Gnus. Of course I could just define another authentication source in auth-source.el as you suggest. I thought that extending secrets.el was the more logical choice since much like the org.freedesktop.secrets interface, the Keychain Services API provides a Login key chain along with the possibility of using an application defined keychain. I am willing to be over ruled though. Which approach should I take? Whichever approach I take, I may need some help writing the Lisp code necessary for my change. While I know enough Lisp to perform simple tasks, I am definitely NOT a Lisp programmer.
