I have a Ubuntu server running Samba 3.4.7 that I am successfully able to connect to. I set the smb.conf to include
winbind enum users = Yes
winbind enum groups = Yes
winbind offline logon = Yes

but still if I am disconnected from the network I am unable to log in to Windows 7. Is there a way to allow Win 7 Pro to cache the credentials for offline logons?

Thanks,
Sean
