The method escapeFilterValue() does not exist on SimpleSAML\Module\ldap\ConnectorInterface. Since it exists in all sub-types, consider adding an abstract or default implementation to SimpleSAML\Module\ldap\ConnectorInterface.

It seems like $attr can also be of type null; however, parameter $array of array_map() does only seem to accept array, maybe add an additional type check?
