------------------------------------

             Summary: AirflowConfigParser fails to override has_option from ConfigParser, causing broken LDAP config
                 Key: AIRFLOW-1749
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1749
             Project: Apache Airflow
          Issue Type: Bug
          Components: configuration
    Affects Versions: Airflow 2.0, Airflow 1.8
         Environment: Ubuntu 16.04
            Reporter: Nick McNutt
            Priority: Minor


In configuration.py, class {{AirflowConfigParser}} fails to override {{has_option}} from {{ConfigParser}}.  This breaks the following in ldap_auth.py:

{{if configuration.has_option("ldap", "search_scope"):
            search_scope = SUBTREE if configuration.get("ldap", "search_scope") == "SUBTREE" else LEVEL}}

This code fails to consider whether any environment variable (e.g., {{AIRFLOW__LDAP__SEARCH_SCOPE}}) or command override's are set, meaning that LDAP configuration cannot be entirely set up through environment variables.
