We needed the script in a support case, and it was not properly working. /usr/share/univention-directory-listener/univention-get-ldif-from-master.py Workaround was sed -i '/--schema/{s/replication.SCHEMA_FILE/SCHEMA/}' \ /usr/share/univention-directory-listener/univention-get-ldif-from-master.py but we needed the script on each server, so not a useful workaround.
