This may actually be a pam_krb5 bug. What are the contents of your /etc/pam.d/imap file? My imap PAM config looks like: [(26) root@vir /etc/pam.d]# cat imap #%PAM-1.0 auth sufficient /lib/security/pam_krb5.so auth required /lib/security/pam_unix.so shadow try_first_pass account required /lib/security/pam_unix.so session required /lib/security/pam_krb5.so This should be fixed with the current set of imap errata packages. |
When using imapd with pam_krb5.so for authentication, imapd doesn't clean up the ticket caches in /tmp. This leaves behind a huge mess on a busy system.
