[PERDITION-USERS] Errors in perdition IMAP auth to courier-imap

Hello, We have deployed Perdition 1.19rc4 to proxy user requests during a migration with popmap via LDAP. While POP works fine, we are seeing authentication failures through Perdition to the Courier IMAP, as shown below. I see there was a similar issue reported in build 1.18, in early 2011, but it was thought to be fixed since then. That post is at: http://lists.vergenet.net/pipermail/perdition-users/2011-January/002468.html Am I missing an IMAP configuration setting or is this still a bug? Any help you can offer is much appreciated.
