All, I appreciate the help you have given me on this and I am pretty sure I am like one or two changes off the correct path. When I do the radtest, it always tells me that: [root@cleveland ~]# radtest atkinsd xxxxx lhost 1645 xxxx Sending Access-Request of id 168 to 127.0.0.1 port 1812 User-Name = "atkinsd" User-Password = "xxxxx" NAS-IP-Address = 255.255.255.255 NAS-Port = 1645 Re-sending Access-Request of id 168 to 127.0.0.1 port 1812 User-Name = "atkinsd" User-Password = "xxxxx" NAS-IP-Address = 255.255.255.255 NAS-Port = 1645 rad_recv: Access-Reject packet from host 127.0.0.1:1812, id=168, length=20 rad_decode: Received Access-Reject packet from client 127.0.0.1 port 1812 with invalid signature (err=2)! (Shared secret is incorrect.) I have checked and double checked the shared secret in Users, sql.conf, radiusd.conf. Any ideas? Thanks again
