Description Felix Botner

After purge_s4_computer.py there are still some references/objects in the samba database and the server is still member of the drs replication.

-> purge_s4_computer.py
-> univention-s4search --cross-ncs cn=SERVER
"CN=SERVER,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,BASE" 
-> samba-tool drs showrepl

After deleting these objects (there are some child objects) and a running "samba-tool drs kcc" the server is gone.

So there is some more work to to in purge_s4_computer.py. But, we should use the "new" samba-tool demote command for that s4 part.

samba-tool domain demote [options]

Demote ourselves from the role of Domain Controller.


Options:
  -h, --help            show this help message and exit
  --server=SERVER       writable DC to write demotion changes on
  -H URL, --URL=URL     LDB URL for database or target server
  --remove-other-dead-server=REMOVE_OTHER_DEAD_SERVER

AFAIK drs kcc is done internally every few minutes. So it will be removed automatically.
