Problem
Some groups cannot be synced with the OX Connector.
This is the traceback:

Analysis
Some users were missing in the /var/lib/univention-appcenter/apps/ox-connector/data/listener/old/ directory. They have been removed from that directory at some point. Those missing users existed in OX though. You can check if there are missing users in the old directory:
univention-ldapsearch -xLLL univentionObjectType=users/user entryUUID | grep entryUUID | awk '{print $2}' | xargs -I{} stat /var/lib/univention-appcenter/apps/ox-connector/data/listener/old/{}.json 2>&1 > /dev/null
Solution
We re-synchronized those users and the group could be provisioned succesfully.
