Rowland, this happened at least 3 times already, all after upgrade.
I really regret that I followed your suggestion and did that force-thing,
but at that time I didn't know it will be a common problem.  At least I
were able to try to figure out what's going on. Yes I need help from
someone who understands this part of samba and/or protocols involved,
but I sure am able to perform quite some debugging without requiring
to be babysitted with every step. Now once I "fixed" my situation with
force, I don't have that issue anymore and can't find out what was
actually wrong.

The problem here is common and it will be much more common once people
start upgrading. Maybe there's a bug in debian packaging, maybe it is
a prob with samba code, maybe something  else, I dunno.

Lorenzo seems to be able to do some basic debugging too.. maybe we
can use this opportunity and try to understand what is going on,
instead of using the force?
