How to disable anonymous on Apache Nifi 1.25

[#1]

We have been using nifi with anonymous enabled with initial development.

Now the requirement is to disable anonymous and have user based authorization / authentication.

To start with, we want to disable anonymous and have single-user-authorizer.

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.

Update nifi.properties with false flag as shared below. But still we are able to access without credentails.

nifi.security.user.authorizer=single-user-authorizer
nifi.security.allow.anonymous.authentication=false
nifi.security.user.login.identity.provider=single-user-provider
nifi.security.user.jws.key.rotation.period=PT1H
nifi.security.ocsp.responder.url=
nifi.security.ocsp.responder.certificate=
