 Thank Rowland for write me;
I run the comands, this are the result:

[root@gtmpve nagios]# net rpc rights list privileges -Uadministrator
Enter administrator's password:
     SeMachineAccountPrivilege  Add machines to domain
     SeTakeOwnershipPrivilege  Take ownership of files or other objects
     SeBackupPrivilege  Back up files and directories
      SeRestorePrivilege  Restore files and directories
     SeRemoteShutdownPrivilege  Force shutdown from a remote system
      SePrintOperatorPrivilege  Manage printers
      SeAddUsersPrivilege  Add users and groups to the domain
      SeDiskOperatorPrivilege  Manage disk shares
      SeSecurityPrivilege  System security


[root@gtmpve nagios]# net rpc rights list accounts -U'ATGTM00\administrator'      
Enter ATGTM00\administrator's password:
BUILTIN\Print Operators
No privileges assigned

BUILTIN\Account Operators
No privileges assigned

BUILTIN\Backup Operators
No privileges assigned

BUILTIN\Server Operators
No privileges assigned

ATGTM00\Domain Admins

SeSystemProfilePrivilege
SeProfileSingleProcessPrivilege
SeIncreaseBasePriorityPrivilege
SeLoadDriverPrivilege
SeCreatePagefilePrivilege
SeIncreaseQuotaPrivilege
SeChangeNotifyPrivilege
SeUndockPrivilege
SeManageVolumePrivilege
SeImpersonatePrivilege
SeCreateGlobalPrivilege
SeEnableDelegationPrivilege

Everyone
No privileges assigned


 It look like the Domain admins yes have the 'SeDiskOperatorPrivilege' privilege.
 I change the group of the share with chgrp and try from Windows RSAT. I saw the Doamin admins group with Special permissions set; but can chage anything in Secutiry tab. In Share permissions tab yes.

 Now I get this: 


[root@gtmpve nagios]# getfacl /test/compartir/
getfacl: Eliminando '/' inicial en nombres de ruta absolutos
# file: test/compartir/
# owner: root
# group: ATGTM00\134domain\040admins
user::rwx
group::r-x
other::r-x

[root@gtmpve nagios]# ls -lda /test/compartir/
drwxr-xr-x. 2 root ATGTM00\domain admins 6 abr 13 08:29 /test/compartir/

 The group ATGTM00\134domain\040admins have not permissions to write in this directory. Is that right?
