So how do I tell either Samba or Bind to accept normal Zone updates from dhcpd? Also. my original problem: #wbinfo -S S-1-5-21-2139989288-483860436-2398042574-2000 failed to call wbcSidToUid: WBC_ERR_UNKNOWN_FAILURE Could not convert sid S-1-5-21-2139989288-483860436-2398042574-2000 to uid Is still here.
