We are trying to set up and ssh server and a VPN server to both use the same radius server. We are currently using freeradius-1.0.1-3 with EL4.4 . It works fine with our Cisco 3015 VOPN concentrator. It's not working so well with our EL4.4-based ssh server. I doanloaded the pam_radius_auth source and built and installed per http://www.hoei.com/2007/09/linux-sshd-authentication-to-external-radius/ and the INSTALL file that came with the software. I can get radtest to work just fine from the ssh system, but when I try to authenticate via ssh onto that system, it fails. Running debug on the server, I was seeing this: User-Password = "\010\n\rINCORRECT" I found something on the list saying this could happen if the user wasn't in the passwd file on the ssh box. I added the user there: meo:x:9999:100::/home/meo:/bin/tcsh and now the radius server is happy. It claims to be authenticating OK (we use shadow passwd on the radius server, but I did not make shadow entries on the ssh box), but the ssh login fails. Any ideas? Thanks, Miles
