[Samba] Can't set ACL on Samba

Hi everybody,

i'm getting mad configuring samba to join an ADS, resolve domain  
users and groups and set ACLs via windows explorer on a share mounted  
with POSIX ACL and extended attributes.

At the point where i am, i've managed to get Samba join correctly the  
domain with idmap_rid backend working fine.

I can correctly set (add, remove, modify) file acls and extended  
attributes via bash, but when i try to simply add a user permission  
on a file or directory via the windows explorer security settings i  
get in the log (level 3):

attr, acl, libattr, libacl to have compiling with acl support.

What i'm i doing wrong?

Thanks in advance for any help.

I remain at disposal for any further information.

[Samba] Can't set ACL on Samba

My samba 3.0.20b is compiled with ads and acl support. Kernel is a
2.6.14.2 <http://2.6.14.2>, compiled with acl and extended attributes 
for used
filesystems.
The system is running a slackware 10.2. I had to rebuild from source
attr, acl, libattr, libacl to have compiling with acl support.

plus

/[root@ariannadb EHD]# smbd -b | grep ACL
   HAVE_SYS_ACL_H
   HAVE_POSIX_ACLS
[root@ariannadb EHD]#
/
I doublechecked that.

I also found out that the groups created by the idmap_rid backend do not 
reflect entirely the real groups in the Active Directory domain.

Thanks for the help.

Regards,


Alberto
