The "right" -- for some value of "right" -- solution is to convert  
everything to LDAP.  That would give you the access control you need.   
Barring that you have only one choice with several flavors: maintain a  
local access control file.  You can do this by disabling NIS and using  
a local password file.  You can do this with a custom PAM module that  
queries a local access control list.  There are other variations but  
they all revolve around maintaining some kind of access control list  
outside of NIS.

I'd suck it up and go with the local password file.  It's a pain but  
it won't break with OS updates.
