[Samba] AD: smb.conf of newly joined DC

[mathias dufresne]

Hi all,

When provisionning a Samba 4 AD domain with --use-rfc2307 the option
"idmap_ldb:use rfc2307 = yes" is added to our first DC's smb.conf.

When joining a Samba4 to a domain to make it a DC we can't
use --use-rfc2307 and "idmap_ldb:use rfc2307 = yes" is not automatically
added to newly joined DC's smb.conf.

Question 1: is this option useless on non-FSMO DC?

Question 2: if this option is not useless on non-FSMO DC, don't you think
smb.conf should be copied from working DC at "join" time?

Question 3: as this could be a choice, is it advised to first copy smb.conf
from working DC to newly joined DC then start Samba service on this newly
joined DC or is it advised to first start Samba with default smb.conf then
stop it, copy smb.conf from working DC and start Samba again?

Thanks and regards,

mathias
