I see, thanks. I plan to have two DCs online, so I could put them down
for maintenance one by one, without stopping entire domain services over
Actually, I was asking about something different. ATM, in Samba 3 NT4
domain (LDAP backend) I can do the below to manage the domain data:
- export data with slapcat
- do whatever I need with the above dump (if necessary) and load them
again with slapadd
The above is very convenient - when domain data were damaged, I could
fix the human-readable dump and re-load it to bring things back in order.
Is something similar available for Samba 4 (below 4.9)? Dump data in
human readable format and re-import when necessary?
