How to configure Radius to provide Linux user permissions and rights

[Michael Martinez]

A radius 2.2.9 server authenticates Linux users via the pam module. Is it
possible for Radius to not only very password, but also provide the users
with their Linux permissions - their group memberships and other such
things? If so, how to configure this?

Other traditional ways of doing this, such as ldap or NIS, work by
interacting with PAM or nsswitch, and can be cached in nscd. But I'm not
seeing a way to integrate radius into this. Different sources online
mention that radius can pass group membership back to the client but they
don't explain how to configure it.

Any help appreciated,
Michael
