Re: [Samba] chrony configuration for secondary samba DC




Correct. But it doesn't answer my original question. How should one to
setup NTP server at his Samba DC that doesn't hold PDC emulator FSMO
role...
Moreover, what package is responsible, in this case, of machine time
sync: NTP server / client or SAMBA as AD client?
Dose samba menage time synchronization by itself or it delegates this
task to the local NTP server?
