[Samba] Problem with ACL and Samba

[Felipe Tocchetto]

Hey Greg, thanks your reply:

I put the defaults acls in my previous email, take a look:

[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::---

The default acls have the entries:

group:suporte:rwx
group:administ:rwx

But after I edit the file, one of these disapear.

I read something about a samba bug:
https://bugzilla.samba.org/show_bug.cgi?id=2346

But it has been fixed a long time ago.

Any tips?
