Re: [gdm-list] GDM user authentication problem

["Aldo Foot" <lunixer gmail com>]

I also thougth the problem is related to PAM. However if I reset the system
when the problem happens I can login that one time, but not a second time.
It's really abnormal.

I inspected GDM's pam config file but nothing jumps out at me. See below:

cat /etc/pam.d/gdm
auth required pam_listfile.so onerr=succeed item=user sense=deny
file=/etc/bastille-no-login
#%PAM-1.0
auth       required     pam_env.so
auth       required     pam_stack.so service=system-auth
auth       required     pam_nologin.so
account    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth
session    optional     pam_console.so

I have seen one or two references elsewhere in which someone either added
a line or took one out. But which one?

Also, I was checking GDM with /usr/sbin/gdmsetup, but nothing seems
out of place.
I feel like I'm looking for a needle in a haystack.

Thanks Brian.
