Samba & PAM problems

I've configured samba & winbind correctly (it would appear), and I see my win domain accounts just fine. When I try to add PAM to the equation, I don't have any success in logging in using a domain account. I followed a tutorial found here: http://www.linuxquestions.org/questions/showthread.php?s=&threadid=155887&highlight=Suse9+samba+integration+with+Microsoft I'm using SEL 9, and I'm not looking so much to login to SEL using a win domain account as I am in creating shares with win user/group permissions on the SEL 9 box. Does anyone have a working PAM configuration they could share?
