samba - Dec 2006 - Problem authenticating user from trusted domain

Hi all,

i have a samba-server in domain named "WW300" and a user from domain
"WW002"
tries to connect to one of my shares but fail. so i switched on logging and
looked what happens:

anyone having an idea what's happening here? why is my user from ww002
mapped to
ww300?

thanks a lot,
christian

P.S.: samba is version 3.0.10 (i already tried it with 3.0.23c, same
problem....)
