Even though the tests only use authn.db, the run.properties file set up by prepare_test.py specifies that authn.simple should also be installed.
For now, the need for authn.simple should be removed.
In the longer term, I would prefer to use authn.simple rather than authn.db as it is simpler to set up, but this will need to be coordinated with changes to icat-ansible to get the CI tests passing, so this is currently not as simple as it might appear.
