Enabling idmap_ldb:use rfc2307 = yes on 2 DCs

[Daniele Dario]

Hi list,
is there a way to enable idmap_ldb:use rfc2307 if I already have 2
working AD DCs in my domain?

Should I just add the line on smb.conf and restart samba on the DCs?

I've also read that nss should be configured for winbind: does this mean
that I have to modify /etc/nsswitch.conf? If yes, could someone point me
in what and how to change it?

Thanks in advance,
Daniele.
