Hi all.
Thinking about the future upgrade to 5.2 I’ve looked at an old system diagnostic that has hung around for a long time. It is “LDAP schema files are not properly registered”.
Old packages and Apps registered schema files by copying the files locally into a certain directory.
The preferred way now is to register them in LDAP; this is less error prone in situations like backup2master.
The following files seem to be registered in the old way:
* /var/lib/univention-ldap/local-schema/univention-corporate-client.schema
There is a button to register the single missing schema file however, given its an old UCC schema from when we had that installed back around the v3-v4 transition I don’t actually want to keep it.
I can find the following wiki around removing schema extensions that look to already be registered in LDAP.
I can’t find any UCC attributes in the LDAP. Should be safe to remove the .schema file given it was never ‘properly registered’ (taking backups/snapshots of course).
