When starting an exam i get the following error for every exam user in management-console-module-schoolexam.log

The messages can be ignored. They are printed as long as the users aren't replicated to the system. Here is the full log where one can see that they exists after a while. There is a for loop for 300 seconds.

You can REOPEN the bug if the message should be hidden. I would say that we should use lo.get(user_dn) to check if the objects are replicated and after that use utils.distribution.openRecipients(). 

grep -e replica -e 'No such' -e exam/start --color=always /var/log/univention/management-console-module-schoolexam.log
