did you go into the system setup utility and enable NIS authentication?
(or use authconfig from the command line).  That's the best way
to ensure that PAM is configured correctly to use NIS and that's likely 
the problem.

(does "id" on a yp user name work?)
(does "su" to a yp user name work?)
does "nis" appear in /etc/nsswitch.conf? (setup will do that).
