Samba PDC and linux desktop authentication

[Jim Patterson]

I am trying to set up a linux desktop to authenticate with my SambaPDC.  
Whenever I enter wbinfo -u and wbinfo -g the information for my domain 
is shown correctly.  I enter the information for the domain and PDC in 
windbind section of system-authentication-config.  When a user logs in, 
I see the following errors in /var/log/messages.
