I doubt that there is something specific. Netgroup schema is a standard
2307.
I suspect that AD uses this schema and the client software just uses
LDAP client connection to get this info.
So in general case it should be the question of pointing the LDAP search
to a different server.
Of cause if the client software has some AD related assumptions like
base DN hardcoded then there will be a problem but app developers 
learned this lesson more than 10 years ago so I hope this is not the case.
