[Samba] Specify or rename 'Administrator' name (cn) for DC ?

[CpServiceSPb .]

Hi all.
Is it possible to change DC administrator name from 'Administrator' to
something else, for example, to 'DomaAdministr' ?
If it is, is it possible via command-line or via LDAP browsers only ?
If it do via LDAP browser (of course cn will be changed) , will Samba4
contunue to work correctly ?

Also, I offer to add new switch to Samba4 DC provision such as 'adminname'
, that is:

Set DC Administrator name during provision, for example:
./samba-tool domain provision --host-name=Main --realm=dom.net --domain=Dom
--host-ip=192.168.0.1 --adminname="MainDomAdmin" --adminpass='passsss'
--server-role=dc --function-level=2008_R2 --use-rfc2307
