[Samba] Samba ACL and Office 2007

[David Vaz]

I am using samba 3.3.2-1 in a debian squeze installation, using ext3
with acl support.

The problem I am experiencing is easy to replicate as I have tried it in
different machines.

In a given share, user "A" is the owner of the folder "test", inside
this folder there is a office file "test.doc" for example. User "B" has
write privileges over file "test.doc" but not over "test". When user "B"
tries to save the office document (using office 2007) an error appears
"Access Denied. Contact your administrator".

# file: test
# owner: A
# group: G
user::rwx
group::r-x
other::---

# file: test.doc
# owner: A
# group: G
user::rwx
user:B:rwx
group::r-x
mask::rwx
other::---

Notice that if the user copy the file to his desktop, modifies it and
later overwrites the original there is no problem.

This error is similar in some ways to this
https://bugzilla.samba.org/show_bug.cgi?id=6160, but i suppose now the
lock over the folder.
