[Samba] Problem with ACL and Samba

[Felipe Tocchetto]

Dear All

I am facing a strange problem that I could not solve, so, maybe you can help
me.

Look at this situation:

I created a new directory with those ACLs (through Samba using Windows XP)

[root at server /home/smb/adm]# getfacl teste
#file:teste
#owner:1002
#group:1006
user::rwx
group::rwx
group:suporte:rwx
group:administ:rwx
mask::rwx
other::---

[root at server /home/smb/adm]# getfacl -d teste
#file:teste
#owner:1002
#group:1006
user::rwx
group::rwx
group:suporte:rwx
group:administ:rwx
mask::rwx
other::---

My ACLs are right, ok, now I will copy a XLS file to that folder:

[root at server /home/smb/adm]# getfacl teste/excel-test.xls
#file:teste/excel-test.xls
#owner:1002
#group:1006
user::rwx
group::rw-
group:suporte:rwx
group:administ:rwx
mask::rwx
other::---

OK, the samba server inhert the permissions and the ACLs, everything is fine
until now.

But when I edit this file with MS Excel, and save it, look what happen to
the ACLs:

[root at server /home/smb/adm]# getfacl teste/excel-test.xls
#file:teste/excel-test.xls
#owner:1002
#group:1006
user::rwx
group::---
group:suporte:rwx
mask::rwx
other::---

The ACL entry "group:administ:rwx" just have gone after I save the file.

It happens with Windows XP, Vista, Office 2003 and 2007. My samba version is
Samba version 3.0.26a, my SO is FreeBSD 6.2. I installed samba through
Ports.

Anybody knows what is wrong?

Thanks a lot!
