  Yes.  ;-)

  Well, those are all part of "Linux server".

  What you are trying to authenticate are Linux (or Unix) *user
accounts*.   I point this out because getting the terminology right
will probably help you find the information you are looking for.

  Now, while I've authenticated various services running on various
Linux servers using RADIUS, I've never tried Unix user accounts.  But
I expect that's been done, too.  You will almost certainly need to use
a PAM module.  PAM = Pluggable Authentication Modules.  PAM is neat;
it lets Unix pull user account info (along with other stuff) out of
any source you have a module for.

  A Google search for "pam radius" finds lots and lots of good stuff
right away, so I suspect that will lead you quickly to where you want
to be.

  Hope this helps,
