Subject:    [Samba] Default POSIX ACLs masking later permission edits

Hello,

I have recently set up a Samba based file server running 3.0.27a.  This file server is part of \
a Windows 2003 domain, with ACL and extended attribute support enabled, and appears to be \
functioning properly except for one critical issue with the ACLs.

When I try to edit the permissions of a file through Windows, the default POSIX ACL that I set \
up on the filesystem seems to be masking off any future permission edits.  My default ACL (set \
with setfacl) is to allow full control to the domain group "domain users".  If I then try to \
remove the full control permission from a Windows XP workstation, leaving only the read \
permission set, as soon as I click Apply the full control permission comes back!

Using setfacl I am able to remove the offending entries, but as soon as I try to edit a \
different permission through a Windows client, they come back.

Is this the correct behavior?  I have been unable to find any information on this type of \
issue.  If this is correct, could someone please suggest a means to apply a default ACL only \
when files or directories are created, and then allow full permissions editing at a later date? \
I would not have set a default ACL at all, except for the fact that newly created files are \
inaccessable without first setting permissions.

Thank you,

Timothy Pearson
