Hey,
thanks. It’s not obvious from the file itself what the issue is. Please follow the steps written in the following article:
https://help.univention.com/t/what-to-do-if-a-failed-ldif-is-found/6432
The goal is to get the LDAP server to re-try applying the failed.ldif and to observe what the log files contain at that point. That should lead us to the actual error messages, e.g. that the objects exist already or that an attribute isn’t known.
Kind regards,
mosu
