RE: OpenSSH, PAM and pam_radius_auth
Hi Alan, So fix DNS so that it has a name to IP mapping for that host. Or, add that name to IP mapping into /etc/hosts. The module can't do anything if you tell it to use radius1 as a RADIUS server, and the don't tell it where radius1 is on the network. We have entry in the /etc/hosts file for radius1 server, but the pam_auth module is having issues in reading it. You have seen the error, even if we give the IP address, it tries to resolve it to IP again. Alan DeKok. - List info/subscribe/unsubscribe?

RE: OpenSSH, PAM and pam_radius_auth
Hi Johan, Its good to hear that you reached up a level where Radius is working fine. But we are unable to break the jinx, and I am getting the following error when trying to telnet to the box.

For some reason it seems that the account system does not allow the user to login, and once the user has been authenticated, it drops the connection by not allowing sshd to establish credentials for the user. It seems that OpenSSH first tries to authetnicate the user with an empty password (), because if I set an empty password both in the local /etc/passwd, and on the RADIUS server, sshd is able to establish credentials for the user. Note that even with a non-empty password the authentication works, the daemon gets and OK from the radius server. There's a user with that given name in /etc/passwd. Anyone ideas about what could be wrong here?

Hi Alan, Any thought gone on this? Why is the plugin unable to resolve the IP address of the RADIUS server, or trying to resolve an IP to IP? Is that something related to compilation?

Is that host entries in /etc/hosts file wont work for this, do I need a DNS server for RADIUS server name authentication to work with pam_radius_auth.

Check that both are using port 1812, if that is what you are using. Have you edited your telnet pam entry? I'm not familiar with solaris, but that is what I would check. More info would be helpful too.
