It is still not clear to me if it is Hardy clients that are the problem, or the Ubuntu servers. It seems it is the Hardy clients. Can people downgrade their hardy clients to the 3.0.28a-1ubuntu4 version and then try to connect with the Hardy client, while keeping their updated hardy servers at 3.0.28a-1ubuntu4.2 (or 3.0.22-1ubuntu3.7 on dapper and 3.0.26a-1ubuntu2.4 on gutsy)?
