 Title: #540: Fix python3 issue in the integration test
Action: opened

PR body:
"""
With this patch the integration tests can run with python3.

To test make sure $(PYTHON2) in src/tests/intg/Makefile.am is replaced with
$(PYHTON3). Additionally the required python3 modules like e.g. python3-pytest,
python3-pyldap or python3-ldb must st installed.

At startup pytest will print a status line like

    platform linux -- Python 3.5.4, pytest-2.9.2, py-1.4.34, pluggy-0.3.1 --
/usr/bin/python3

where you can check if python3 is really used for testing.
