Very odd issue. Transitioning over to a new samba 3.6.9 (from 3.0.33)
server. Majority of the users are ok, but a handful of users cannot map
their home directories from windows7 clients. Logged into XP their homes
map fine. They pass authentication:

"access denied" and then this in the logs:

Yet on the same machine, other users can map their home directories just
fine. I have checked all I can think of, I'm hoping the community has
some ideas.
