Samba is member server of an w2k SP4 AD domain. A share access right is set for
a user from the windows side. Connection to this share from a w2k SP4 wkstation
as a domain user fails wrongly, apparently because the domain user get a local
SID which doesn't match the domain SID of the user that specify the access right.

I can reproduce it with smbclient -k but it work fine if i don't use -k.
Actually going to security=domain apppear to be a workaround.
Yes, this is a known issue with running in "security = ads" and we are currently
working on it. It will also have an effect on assigning privileges.
