That sounds like samba bug #4620
(https://bugzilla.samba.org/show_bug.cgi?id=4620)
and Debian bug #424046 (http://bugs.debian.org/424046). Yes, even if
you don't use Debian...;-)

While, as far as I know, the bug submitter did not mention in #4620
whether (s)he uses "username map", this is really really similar..

Do you use "security=server"? The problem should disappear if you
switch to "security=domain".
