Hi Andy,

I can't give you a total solution solving your (our, you are definitly 
not alone with this) problem. This problem is a mapping conflict. If you 
try to change the permissions on windows side, you will see in the samba 
log, that it can't map the SID under windows to a UID under unix. This 
will take, I think, a deeper look into the ACL's. I think, that we have 
to use winbind at all, because it makes the SID->UID mapping. Using 
group mapping is recommended, I think, but you have to consider the 
rid's. If you make a usual mapping to the "Domain Users" group without 
defining the rid, the last part of the SID will be generated 
automatically (algorithm mapping, or so).

No solution, but maybe a hint. If you solve it, please post.
