Configuring to use shadow passwords

[Robert Bess]

I have freeRadius 0.4 on Linux-Mandrake 8.1   Radius seems to be running.  When I run radtest with a username that exists in the /etc/raddb/users file it works if I specify a password.   i.e.     bob  Password = "bob"   but not if I try to use a real system user.   i.e.     bob  Auth-Type = Unix   When I do that radtest says: Access-Reject packet from host …   I was wondering if the problem is with the /etc/shadow file.  I uncommented the line in radius.conf where it specifies my shadow file is in /etc/shadow and I have tried setting radiusd to run with group name “shadow” in the radius.conf file.   Is there something special I need to do when compiling radius to let it know I use shadow passwords?   Is there any other reason my server might be rejecting the users in my system password file?   Thanks for any help.                                                                                                              :”
