Since my switch to gnome 3.12, I have a problem with the "Passwordless login trick" .
I have added "auth sufficient pam_succeed_if.so user ingroup nopasswdlogin" to /etc/pam.d/gdm-password.
With previous versions of gnome, when I launched evolution (for example), as gnome-keyring wasn't unlock, I had a dialog asking for the password.
In 3.12, that dialog does not open and so evolution can't retrieve my mails (same with epiphany that can't save passwords).
I have removed the line and it works fine, but I really prefer passwordless logins (especially when switching between users or after idle!)
Do you have a clue what has changed and where I could look at?
