opensuse 12.1 AD offline authentication not working

i just did a fresh install of opensuse 12.1 at work while plugged in via ethernet. i joined to the domain and was able to login as my domain user. i chose the option for offline authentication while doing the domain config because i have a laptop

when i got home that night, i had just suspended so i resumed my lapotop, but found that trying to run a lot of things from the shell got me the message “You don’t exist, go away!”

I rebooted, and when the laptop came back up i was unable to login as my domain user. it had my user on the login screen right, DOMAIN\me but it wouldn’t accept my password, kept saying authentication failure. in the logs i saw

Nov 21 22:11:02 hercules-linux gdm][1596]: pam_winbind(gdm:auth): getting password (0x00000390)
Nov 21 22:11:02 hercules-linux gdm][1596]: pam_winbind(gdm:auth): pam_get_item returned a password
Nov 21 22:11:02 hercules-linux gdm][1596]: pam_winbind(gdm:auth): internal module error (retval = PAM_AUTHINFO_UNAVAIL(9), user = 'DOMAIN\me')

I’m back in the office now plugged in and it’s working fine again.

does anyone know what hte option for ‘offline authentication’ actually does to my config, and how i can double check that it’s in place or do it manually?

Thanks
