The answer is to use netgroup if you use NIS/NIS+. If you do not use
NIS/NIS+, you have to build your own authencation scheme, like Matthew
Stier suggested the logdaemon from TCP_WRAPPER packages.

Hi gurus,

How do I limit logins to only certain groups of users, for example,

hosta: allow group A, B, C, deny group D
hostb: allow group D, deny the rest

Thank you in advance for your helps,

I will summarize.
