Hi,

Please check that you have the following:

For samba4 use rfc2370 and specify the uids gids (using e.g. ADUC), 
copy/symlink the libnss files and allow winbind in /etc/nsswitch.conf
For samba3 use idmap_ad with a range that covers the assigned uids/gids.

If that is configured and don't work as expected please post your 
smb.conf (both from AD and client system) and an ldif for an user 
obtained by ldbsearch.
