Pop3d user lookup problems. (Imapd works great)

[Mycrom]

I have just recently set up a new system running cyrus-imap package along
with postfix and ldap auth using saslauthd. This seems to be working great
with Imap but when I attempted to log in with pop the user fails with
nothing more then "Invalid User". As IMAP is working great and both the IMAP
and POP processes use the same conf file I have not been able to locate what
the issue is.

In searching all of the message forums along with google I have seen a few
posts regarding similar such problems but never a solution. I have provided
session, log, rpm, and conf data below.

Any help would be much appreciated.
