[Samba] windows security of files and folders

[aux]

Hi, i have a samba 3.0.12 PDC (LDAP) with many windows clients. All 
works correctly but when i show properties (security) of one file or 
folder many times i see the SID and not the user or group. I can't 
assign the perms with the windows because i don't see the groups of ldap.

My configuration:


1 samba-3 PDC-LDAP (scripts, bats, etc. This scripts mount shares of 
other samba)
In this samba, if i mount a share and click security of a file i see the 
users but not the groups

1 Samba-3 (other samba, server FS) (shares, data, etc)
In this samba, if i mount a share and click security of a file i don't 
see users and groups)

My groupmap:

# net groupmap list
Domain Computers (S-1-5-21-3984604316-2900431957-2958281145-515) -> 
maquinaspdc
Domain Admins (S-1-5-21-3984604316-2900431957-2958281145-512) -> domadmin
Domain Users (S-1-5-21-3984604316-2900431957-2958281145-513) -> domuser
