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

[Quentin Gibeaux]

Hi,

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
        CN=ypServ30,CN=RpcServices,CN=System
      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$,CN=System,DC=... and in
        CN=Infrastructure,DC=...
      o the user dns-$NETBIOS
      o fSMORoleOwner msDs-masteredBy msDS-IsDomainFor masteredBy in
        DC=... entry

Any clue to update the server's hostname ?

Thanks,
