There's your problem.  What do you have in the LDAP entry for uid for
jlambert?  From what I see above, it looks like 1000.  Maildrop does a
setuid to the user that mail is being delived to and since the mail
spool is owned by uid 91, with only user permissions, it is unable to
enter the maildir that you've specified.

If you're not trying to do virtual users for e-mail, then just chown the
maildir to jlambert (1000).  Otherwise, change the uid attribute in LDAP
to 91 (vmail).
