cyrus2-imapd seems to be having problems authenticating users via PAM. When I try to log in via "telnet mailhost 110", I get an error message similar to the following (regardless of whether I enter a valid or an invalid password):
mailhost:~# telnet mailhost 110 Trying W.X.Y.Z... Connected to mailhost.domain.nam. Escape character is '^]'. +OK mailhost Cyrus POP3 v2.0.16 server ready user ddkilzer +OK Name is a valid mailbox pass XXXXXXXX -ERR Invalid login quit +OK Connection closed by foreign host. mailhost:~# When I run strace(1) on the pop3d process, I see it looking for /etc/pam.d/pop an /etc/pam.d/other, but not /etc/pam.d/cyrus (as it is installed). It (or some library code it calls) has problems accessing /etc/shadow, which probably means that PAM can't access that file because pop3d is running as the 'cyrus' user, not 'root'. Note that I *have* created the 'user.ddkilzer' mailbox using cyradm. The next step for me is to look at the various RPMs (Red Hat's and a couple others) to see what kinds of patches they use for PAM support and general bug fixes. http://rpmfind.net/linux/rpm2html/search.php?query=cyrus-imapd Dave
