Some screenshots and more details on what you see may be helpful here.
Here are some things to check first:
- Are you seeing a login screen when you try to access the NiFi URL?
-- If so, what do you see after providing your kerberos login credentials?
- Are you running a NiFi standalone instance or a NiFi cluster?
- What are you using as your authorizer?
-- Default NiFi internal file based authorizer?
--- Do the users.xml and authorizations.xml files contain the proper entries?
-- External authorizer such as Ranger?
--- Where the proper authorizations granted for your users?
- What do you see in the nifi-app.log when you try to login?
Thank you,
Matt
