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
