@girishchalke can you provide more information on your cluster and which method you utilized to configure LDAP? Based on my quick read of the documentation for Authenticate Hue Users with LDAP it may be of use to others who may be able to assist.

Thanks for your response.

 

This is a standalone installation of hue on AWS EMR server and we manually configured ldap configuration to sync users from our organizations LDAP server.

 

We are able to add LDAP groups and able to import users within group once. We also set sync_groups_on_login=true so how groups can sync up everyday.

 

however when user is trying to log in, hue is throwing duplicate entry which means its able to identify user in LDAP but not validating it in local db before attempting to insert.

 

as i understand "sync group" will NOT import new users or delete existing user from ldap group so does it mean large organization should manually remove users?
