Unable to seed access policy on NIFI-1.16.0 and User_logs are also not getting generated

[#1]

HI Team,

System Env Details: I am trying setup NIFI on AWS
3 node cluster
NIFI version:  1.16.0

Primarily I tried to setup 1 node with single-user-provider on AWS with NIFI-1.16.0 and able to perform each and every action. It is working fine.

Then I tried to setup 3 node cluster on AWS,
What went well.
1. Configured zookeeper in nifi.properties and Statemanagement.xml and able to formulate a cluster and cluster coordinator setup is successful.
2. using nifi.security.user.authorizer=managed-authorizer
3. Successfully able to integrate with SAML and able to login as a Admin user.

What went wrong:

1. Except User-logs, all other logs are getting generated (app, request, bootstrap)
2. When I have logged in as an Initial Admin Identity, Ideally I  should be able to add users and policy to them. However, I am getting  insufficient permissions while performing any action. (add policy, delete used, edit user, logout etc...)

Any help would be highly appreciated.

Assuming you have NiFi configured to run securely (HTTPS enabled) then the nifi-iser.log should be generated.  I'd suggest inspecting the logback.xml to make sure there are no mistakes in the appender or loggers setup for the nifi-users.log.

Thanks,

Matt

Thank you for pointing out logback.xml, now am able to generate the users.log.
