> 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.
