Check the /etc/nsswitch.conf file and make sure you have THESE lines
uncommented:

	passwd:    db files nisplus nis
	shadow:    db files nisplus nis
	group:     db files nisplus nis

Make sure these lines are commented out:

	#passwd:     files
	#shadow:     files
	#group:      files

You want the first set to be active to check against the NIS server.
The second group will only check passwords and such against the local
files (which is the default if you did NOT specify NIS during the AS3
installation and added NIS later).
