The bug is present in Thunderbird 24.2.0 running on Kubuntu 12.04.4. Running nscd appears to work around the issue, but I haven't tested it thoroughly for side effects.
I find it somewhat ironic that a nearly nine year old bug of this magnitude has status: NEW.
Software versions (all from Ubuntu repos):
$ aptitude show thunderbird | grep Version
Version: 1:24.2.0+build1-0ubuntu0.12.04.1
$ aptitude show libldap-2.4-2 | grep Version
