Hello, I'm trying to write a small program that uses PAM to authenticate a user given a username and password. The program I have uses pam_start and pam_authenticate. What I'm finding on Linux is that pam_authenticate calls the conversation routine once for the password and always returns PAM error code 3. The same program works fine on a Sun machine and fine on an HP-UX machine and I can't see where I'm going wrong. It's almost as if PAM is not linked upto the /etc/passwd file which is the authentication mechanism we use. Should we expect PAM to work straight out of the box or is there something more that needs to be done ? Were any versions of PAM buggy ? Martin
