User groups (LDAP & Co.)

Hi.

That's not a simple question probably. I'm using remote user
informations from ldap, and I have the necessity to make all logged in
users belong to some groups, without modifying ldap.

Every user will belong to his primary posixGroup, but on some machines,
they have to belong also to some local groups, like audio, video,
plugdev... and of course, adding them to passwd and groups it's not so
nice

Can anyone help me?
