[Dovecot] ldap auth problems

I have previously configured dovecot with ldap auth on a fedora setup with no problems.

Now, using RHEL 3 with the same config I get:

dovecot: Jun 30 17:46:07 Error: Auth process died too early - shutting down dovecot: Jun 30 17:46:07 Error: child 16780 (auth) killed with signal 11 pop3-login: Jun 30 17:46:07 Fatal: fd_send(-1) failed: Broken pipe imap-login: Jun 30 17:46:07 Fatal: fd_send(-1) failed: Broken pipe

This doesn't happen when using other kinds of authentication, eg pam

The ldap directory is working fine for other apps so I'm pretty sure that's not it.

I'm using the rpm from dag's repository and even re-compiled to ensure ldap support is there.

Any clues?
