Description Florian Best

2023-09-25 17:50:15 CEST

We should enforce schema removal of UVMM before upgrading to UCS 5.1 / UCS 5.2.

+++ This bug was initially created as a clone of Bug #51955 +++

For UCS-5 UVMM is removed, including the schema. This leads to problems during updates, as OpenLDAP then no longer knows anything about the objectClasses and attributes, which are still referenced by the LMDB:

We should check for it in preup.sh and link to <https://help.univention.com/t/remove-ldap-schema-extensions/6443>.
