Comment 24 for bug 64301

I am having a problem like this with gnome-screensaver and libnss-mysql-bg under Hardy Heron, but I am not sure if it is the same problem.

Users with an entry in /etc/shadow can unlock just fine, but any user who is authenticated via libnssmysql fails. However they can log in and still have thier session back if they pick switch user and login with the same username and password.

My /var/log/auth.log reports this when I try to unlock gnome-screensaver with libnss-mysql-bg:

Nov 13 17:09:38 p70 unix_chkpwd[6072]: check pass; user unknown
Nov 13 17:09:38 p70 unix_chkpwd[6072]: password check failed for user (sa)
