What does /etc/passwd look like? I've seen this happen in our
environment when a +entry in /etc/password is above the equivalent user
account. Like if "+root..." or "+ at wheel" were above the default root
account.

Incidentally, my /etc/nsswitch.conf looks like this and does work
appropriately with NIS:

group: compat
group_compat: nis
hosts: files dns
networks: files
passwd: compat
passwd_compat: nis
