still not quite there,
on the dc's i can use getent and id on the domain users
i am not able to list all the domain users or group only individual
users or groups that i request,
is this how it getent normally works on a domain controller,
i only see examples of getting the full list from a member server
e.g. testing winbindd user/group retrieval on the
https://wiki.samba.org/index.php/Setup_Samba_as_an_AD_Domain_Member page ?
this as far as i got to,
using s4bind from the linux costa blanca website
all commands executed on the dc
[root at ashanti dc]# s4bind upgradegroup "Domain Users" 20513
### s4bind ###

on the member server i changed the range
idmap config *:backend = tdb
idmap config *:range = 2000-9999
idmap config TISSISAT:backend = ad
idmap config TISSISAT:schema_mode = rfc2307
idmap config TISSISAT:range = 10000-99999
restarted samba daemons
getent passwd returns only local users and
getent passwd nfs-mgr returns nothing.
i expected to see at least nfs-mgr in the output
