Thanks, yes, it works with other passwords with a more ASCII-like
character set. We've got a limit on frequency of password changes, so
I haven't experimented a lot with what works and what doesn't. We've
got quite a few people successfully using X2Go at the minute (meant to
mention in the report, thanks to all the X2Go developers, it's been
incredibly useful!), and this is the first time we've encountered this
problem. If it's useful I could create a non-AD account temporarily to
test variations if it would help.
