Hi, I have a freeradius server running on Ubuntu/Dapper/i386 platform. Version: 1.1.0-1ubuntu2 I have a client which is Ubuntu/Dapper/amd64 architecture. I have installed libpam-radius-auth and set it up with the server. Version: 1.3.16-4. NOTE. 64 bit AMD architecture. What I am trying to do: ====================== Use the /etc/shadow,/etc/passwd file on the server for user authenticatication. I have configure (on the client) /etc/pam.d/common-auth with contents: auth sufficient pam_unix.so nullok_secure auth required pam_radius_auth.so debug I setup /etc/pam_radius_auth.conf with IPaddress_of_server secret-string 3 where the secret string is typable by keyboard. I added the relevant data to the server for this client. Do I need to use the users file /etc/freeradius/users and put the user in that? Doesn't seem to help. Below I have included two logs, from the client, server and my radiusd.conf file (no comments for the latter file). ------------ Log of /var/log/auth.log on client ------------ Aug 22 15:24:37 fe104 sshd[1745]: Invalid user test-walter from 129.97.15.20 Aug 22 15:24:37 fe104 sshd[1745]: Failed none for invalid user test-walter from 129.97.15.20 port 753 ssh2 Aug 22 15:24:41 fe104 sshd[1745]: (pam_unix) check pass; user unknown Aug 22 15:24:41 fe104 sshd[1745]: (pam_unix) authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=cscf.cs.uwaterloo.ca Aug 22 15:24:41 fe104 sshd[1745]: pam_radius_auth: Got user name test-walter Aug 22 15:24:41 fe104 sshd[1745]: pam_radius_auth: Got password ^H ^M\177INCORRECT Aug 22 15:24:41 fe104 sshd[1745]: pam_radius_auth: Sending RADIUS request code 1 Aug 22 15:24:41 fe104 sshd[1745]: pam_radius_auth: DEBUG: getservbyname(radius, udp) returned -1409445184.
