@Jobin George Can you please suggest how to remove anonymous user by getting default login to Nifi UI. I can login Nifi UI with my LDAP user but Nifi is also accessible with anonymous user without password. I wanted to disable it. In ranger policy if I remove {user} from user section then I cannot login Nifi UI with LDAP user and also it doesn't get default login with anonymous. Please suggest. Brief description is mentioned on below link. https://community.hortonworks.com/questions/142667/how-to-give-permissions-to-users-to-access-nifi-ui.html?childToView=145984#answer-145984 ... View more
