Pam has varying degrees of NIS support. I'm most familiar with using it on
Redhat 5.2 in which NIS was partially broken in PAM. (you had to use an
older PAM module to get shadow over NIS working). I beleive this has been
resolved in redhat 6.0. I would assume that pam and NIS work together
quite well on the solaris systems, though I have less experience in that

the unix passwd sync can call "yppasswd" as long as you setup the chat
options appropriately..
