Title: #265: Test for issue #3391 (sss_override doesn't work with files provider)
If I apply the patch on top of #317 the tests pass:
If #317 is committed I would expect that the CI test here will pass as well. I guess the
best way to proceed is to wait until #317 is commited rerun the CI test and if successful
switch this PR to Accepted.
