I have an openldap server using libdb-4.5, but somehow my OS had db-utils for 4.8 and I guess I run the wrong commands as I now get the following error when starting the server. Is there a way to "downgrade" to 4.5 ?

Your question has practically nothing to do with OpenLDAP and everything to do with BerkeleyDB. The answer is in the BerkeleyDB docs, you should read them.

Run db_recover; it will delete the transaction log files when it completes.
