Hi,

your notifier is not running for whatever reason.

Please do:

ucr set notifier/debug/level=4
systemctl restart univention-directory-notifier

Then delete, the object:

udm settings/udm_syntax remove --dn="cn=app_syntax,cn=udm_syntax,cn=univention,$(ucr get ldap/base)"

Try again to join and send notifier.log and listener.log from the times when you tried to join.

Ok, your notifier is not working at all.

Please check the file /var/lib/univention-ldap/listener/listener. Is it empty (size =0)?
If so, follow the steps in this article.

The article related to this issue in 4.4 is currently in development. In case you have a support contract, please open a ticket. Otherwise you will have to wait until we will make this article public. I guest this is done within the next week or so.

Thanks,
Your suggestion resolved the issue with my master and backup domainserver.
However I have the same issue with my domain slave servers.

You could simply try re-joining the slave servers by running univention-join. The join process will re-download everything from your DC Master. That’s safe to do as no user data will be lost. That being said, if the join process fails for whatever reason the server won’t be usable until that problem’s been resolved. If your slaves run as VMs, simply create a snapshot before joining again.
