UCS - Univention Corporate Server

#1

Hello,

Have multiple ucs servers 5, samba-ad. Domain, backup domain, and secondary servers.

The last one i added is havings issues with the replication, the error is

Last attempt @ Thu Oct 19 11:54:34 2023 WEST failed, result 2 (WERR_FILE_NOT_FOUND)

Already search in the forum but can’t find a solution, one thing that i can identify is that CN=NTDS Settings, for the new server don’t exist…
It is possible to create that entry?

I already join the server multiple times, no success in the replication issue, but the join always end with sucess

This is the rsat tools when select secondary server on site 2

As mentioned earlier samba-tool drs shworepl reports errors, however the slave dc appear to be syncs with the others, can’t underdant how to solve the issue that is missing “arrows” from all the servers to the new slave dc…
