[Samba] maximum ad domain controller unavialability time

[Zhuchenko Valery]

Hi, all.

What is greatest period for AD DC (non FSMO) can be unavailable, for
example, because network segment is unavailable for long time (3, 4 weeks)?
Is the controller will be removed from AD automatically?
And what to do after this network segment will become available?

I have read about tombstoneLifeTime attribute of Directory Service
(Configuration, Services, Windows NT), which default value is 180 days.
But what is about replication?

Thank you for your explanation.

Best regards,
Valery
