I have a seperate UCS instance running kopano4ucs.
On this member server I’m facing the issue that the univention-directory-listener service always fails to start since last errata update (currently running 4.2-3 errata305).
If I start the service via systemd it starts as expected and it seems to be fine.
I’ve already set debug level to 4 but only entry in log on reboot is: LISTENER ( WARN ) : received signal 15
I’m not sure I understand the problem. You’re saying that starting the listener manually works? Therefore I assume that it just fails to start during the boot sequence?
Please post the journal content for the corresponding service unit for the current boot: journalctl -b -u univention-directory-listener.service
Have had also problems like this after the latest upgrade. And the LDAP-Sync does not work on the Kopano server
I had to force a re-join of the Kopano Server in the UMC for this. After the succesfully re-join all was running proper and also the broken LDAP-Sync from the UCS-Master to the Kopano-Backup works as expected
