Setting User Status
User status indicates whether the user is active and should be allowed to log into Ambari or should be inactive and denied the ability to log in. By setting the Status flag as Active or Inactive, you can effectively "disable" user account access to Ambari while preserving the user account information related to permissions.
To set user Status:
On the Ambari Administration interface, browse to Users.
Click the user name of the user to modify.
Click the Status control to toggle between Active or Inactive.
Choose OK to confirm the change. The change is saved immediately.
