In the master branch in git at the moment a complex filter get's incorrectly converted. For example the filter '(&(uid=kouk)(givenName=Konstantinos))' will become '(&(uid=kouk)(&(uid=kouk)(givenName=Konstantinos)))'. In this case there is no error because the filters are logically equivalent. But this might not always be the case. The attached patch fixes this behaviour.
