Summary: Ability for auth plugins to specify a URL for users to edit their profiles, similar to the change password url.
Explanation: We have an auth plugin that does SSO from our main site, which pulls in all the needed profile information. We currently have the permission to edit your own profile turned off for all users, but it would be nice if auth plugins could specify a url for users to edit their profiles from an external site. I see this behaving in much the same way as the change password url that is currently available.
If this is something that sounds reasonable and has a good chance at being accepted, I would be willing to write this and submit a patch (but may not go through the trouble otherwise).
