             Summary: Bulk delete all external users & groups in Ranger with REST API
                 Key: RANGER-4230
                 URL: https://issues.apache.org/jira/browse/RANGER-4230
             Project: Ranger
          Issue Type: New Feature
          Components: Ranger
    Affects Versions: 2.4.0
            Reporter: Abhishek Kumar
            Assignee: Abhishek Kumar
             Fix For: 3.0.0


Ranger admin should have option to clean up all the users from ranger DB. 

Due to incorrect ranger usersync configuration, specially using LDAP/AD, large number of users and groups end up in ranger. 

Large user/group and mapping tables have the potential to cause issues related to ranger admin OOM. Existing REST APIs for deletion are slow and only allow one user/group deletion at a time.


A Ranger API option to clean up external user and groups (or bulk delete user/groups) will be much helpful to address the issues indicated above.

This Jira only tracks changes for the REST API, a UI option can also be enabled as part another Jira to use the same functionality.
