Use the pure-python ldap3 library, which eliminates the need for a system dependency. Offer both a `search` and `simple_bind` mode, for more sophisticated ldap scenarios. - `search` tries to find a matching DN within the `user_base` while employing the `user_filter`, then tries the bind when a single matching DN was found. - `simple_bind` tries the bind against a specific DN by combining the localpart and `user_base` Offer support for STARTTLS on a plain connection. The configuration was changed to reflect these new possibilities. Signed-off-by: Martin Weinelt <hexa@darmstadt.ccc.de>
