@itninja  Did you configure your NiFi to use HTTPS or is still configured for HTTP? In order for NiFi to support user authentication and authorization it must be secured over HTTPS. Could you share some screenshots so I better understand what you mean by: Manage to create Administrator user with the set user script. Able to login with Administrator. But the anonymous is still enabled. Code created user Administrator is still visible with anonymous user. Please help our community thrive.
