Bug is still present in Lucid with all the latest updates installed.
Although the workaround by installing libnss-ldapd or nscd seems to work - according to above comments -, this is not an acceptable solution as it interferes too deeply with the system (changing fundamental system internals just to get a specific client program working).
This problem first appeared with Lucid; in Karmic Thunderbird worked fine with exactly the same system configuration.
