[Novalug] LDAP and Ubuntu 14.04

Is anyone using LDAP on Ubuntu 14.04?  I have a workstation that was
known to work (more or less) with an LDAP server for authentication.
I upgraded to Ubuntu 14.04 and it more or less works still except for
one important exception.  I cannot unlock the screen.  That makes it
a full show stopper for me.

The really odd part is that after some investigation, I tried another
user on the same system and everything works fine.  There must be
something whack-a-doodle with my account, but I don't see it.  I
deleted every instance of 'mark' in the /etc/group file too in case
something was causing the issue.

Logs for authentication fall into /var/log/auth.log.  The logs for
me failing and for the other account working look the same in there.
I managed to turn on debug output and there's not anything useful there
either.  The only extra entry is found in /var/log/syslog and it says:

	Sep 10 22:42:17 mark compiz: pam_ldap: error trying to bind as user "uid=mark,ou=People,dc=winksmith,dc=com" (Invalid credentials)

It's my understanding that it's not supposed to be trying to bind as
me.  My /etc/ldap.conf file clearly states that binding is to:

	rootbinddn cn=admin,dc=winksmith,dc=com

I compared all the entries on the LDAP server.  I looked for my name
in every configuration file i could find.  It all looks good.

I couldn't come up with search terms to solve the problem for me.

why is it trying to bind mark@winksmith.com, but only for me?  what gives?
