[Samba] 3.0.14a +ACL: unable to delete or rename folders

[Mike Duhm]

Hi,

We are running samba 3.0.14a on Debian sarge, kernel 2.6.8-1-686-smp, 
xfs filesystem and have just noticed the following error:

Only the owner is able to rename or to delete folders on our share 
although several groups have full access to them and to the parent 
folder. Deleting or renaming files (same ACL by using default ACLs and 
inherit acls = yes) is working correctly.

For example user "bob", member of groups "dfm", "smbusers" and "admin", 
is not able to delete folder "somedir", owned by "alice" having 
following ACLs.

# file: somedir
# owner: alice
# group: smbusers
user::rwx
user:backup:r-x
group::---
group:admin:rwx
group:dfm:rwx
mask::rwx
other::---
default:user::rwx
default:user:backup:r-x
default:group::---
default:group:admin:rwx
default:group:dfm:rwx
default:mask::rwx
default:other::---

But he is able to create, modify and delete any files, also having 
"group:dfm:rwx", inside it without being their owner. The problem only 
occurs with  folders  not owned by "bob".

Any suggestions?

Thanks a lot for any help !

regards,
Mike
