Postfix and Cyrus-IMAP interactions on x86_64

The file /etc/postfix/ of postfix-2.1.5-4.2.RHEL4.x86_64 contains a hard-coded path to Cyrus-IMAP LMTP deliver agent, /usr/lib/cyrus-imapd/deliver. However, this causes problems on x86_64 systems since Cyrus-IMAP LMTP deliver agent path is /usr/lib64/cyrus-imapd/deliver.

Fixing this problem is easy: just edit /etc/postfix/ and replace /usr/lib/cyrus-imapd/deliver with /usr/lib64/cyrus-imapd/deliver.

I have filled in a bug report against Red Hat’s Enterprise Linux 4:

Cyrus-IMAP and PAM interactions on x86_64

In Red Hat Enterprise Linux ES 4.1 Update 3, both /etc/pam.d/imap and /etc/pam.d/pop contain hard-coded paths pointing to, actually /lib/security/ This causes problems on x86_64 since is located under /lib64/security/

A workaround is to modify /etc/pam.d/imap and /etc/pam.d/pop to look like this:

#%PAM-1.0 auth required service=system-auth account required service=system-auth
