Add some tests for using the ldap2 Backend.

Fix a logic problem in ldap2:get_schema() for determining if it can fetch the schema or not. Normally we only want to do this for servers but if you pass in your own connection it will use that.

Fix a logic problem in ldap2:get_schema() for determining if it
can fetch the schema or not. Normally we only want to do this for servers
but if you pass in your own connection it will use that.
