> Key: AIRFLOW-3208
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3208
> Project: Apache Airflow
> Issue Type: Bug
> Components: authentication
> Affects Versions: 1.8.0, 1.8.2
> Reporter: Hari Krishna ADDEPALLI LN
> Priority: Critical
>
> Hello.,
> We wanted to have airflow integration with LDAP anonymously, the LDAP is
> based on either "openldap" or "389 directory Server". Below is the detail
> added in the airflow.cfg :
> {noformat}
> [webserver]
> authenticate = True
> auth_backend = airflow.contrib.auth.backends.ldap_auth {noformat}
>
> {noformat}
> [ldap]
> uri = ldap://nsp-daf178e8.ad1.prd.us-phx.odc.im:389
> user_filter =
> user_name_attr = uid
> group_member_attr = groupMembership=ou=groups,dc=odc,dc=im
> superuser_filter = memberOf=cn=rvd-sudo_all-prd_usphx,ou=groups,dc=odc,dc=im
> data_profiler_filter =
> bind_user = ou=people,dc=odc,dc=im
> bind_password =
> basedn = ou=people,dc=odc,dc=im
> cacert = /opt/orchestration/airflow/ldap_ca.crt
> search_scope = SUBTREE{noformat}
> However, when trying to validate, it failed with below exception, please
> advise what to correct as per provided detail of LDAP as per above ? We only
> use "basedn=ou=people,dc=odc,dc=im" with provided LDAP host and was able to
> access anonymously when tried using jxplorer workbench. We are able to do
> LDAP anonymously both on kibana/elasticsearch/jenkins, however coming to
> airflow, please advise solution.
