[Samba] PDC issue

[Leonardo Rodríguez]

Hi List,

I installed samba 2.2.8 in redhat 9.0 so I decided to configure it as a PDC
I've managed to find that my windows clients use the PDC users but when 
I use the Linux clients I just can log in the machine in text mode but when 
I try to log in the machine using the graphical mode it doesn't work (it
can't 
authenticate the PDC users)....

What am I doing wrong? What am I missing?

Any help will be appreciate it.....

Thanks in advance

Leonardo
