I am having a little trouble with pam. The setup I want is very simple: I don't need shadow access, so I don't need pwcheck (we use NIS) so I just want PAM to be a gateway to the normal routines for accessing /etc/passwd. My current /etc/pam.d/imap is: auth sufficient /usr/lib/security/pam_unix_auth.so account sufficient /usr/lib/security/pam_unix_acct.so I can authenticate fine. The server logs the following after a simple telnet login: Sep 12 16:17:32 server imapd[2253]: login: server.foo.bar[192.168.69.1] user plaintext However, when I try to use an IMAP client to test the server, the following appears in the logs: Sep 12 16:22:54 server pam[2675]: unable to resolve symbol: pam_sm_acct_mgmt I read online somewhere that this symbol error means that the module cannot do session management correctly. I suspect that my /etc/pam.d/imap file is just off, but I don't know which modules to use, so if someone could post theirs or point me in a good direction, it would be very helpful. Thanks. Brendan
