[Samba] Change hostname of the main domain controller of the Active Directory

With Samba4 and Active Directory the hostname of the server is read 
during provision, to set the netbios name. It's even asked to set 
/etc/hostname and /etc/hosts in respect with the chosen domain/realm names.

I've seen that on real windows AD that it's possible to change the 
hostname of the domain controller with netdom command, but is there a 
way to do so on Samba4 ?
The netbios name seems to be referenced in several locations :

  * in smb.conf
  * in the ldb :
      o msSFU30MasterServerName in some entries located in
      o user's profilePath
      o it's own domain controller entry located in
        CN=$NETBIOS,OU=Domain Controllers,DC=...
      o it's RID entry : CN=RID Set,CN=$NETBIOS,OU=Domain Controllers,DC=...
      o fSMORoleOwner in CN=RID Manager$,CN=System,DC=... and in
      o the user dns-$NETBIOS
      o fSMORoleOwner msDs-masteredBy msDS-IsDomainFor masteredBy in
        DC=... entry

Any clue to update the server's hostname ?
