Hi , We have configured Nifi cluster and using OpenId Connect(keycloak<https://www.keycloak.org/>) for user authentication. In Keycloak, here are some of configuration for token in realm settings
* SSO Session Idle 30 Minutes * Access Token Lifespan 1 Minutes The issue is Nifi UI is giving error after every one minute "Session Expired : Your session has expired. Please press Ok to log in again., and this one just after : Unknown user with identity 'anonymous'. Contact the system administrator". Is this due to Nifi is checking session validity using only access_token? >From Keycloak documentation >https://www.keycloak.org/docs/latest/server_admin/index.html#_oidc-auth-flows >access_token is short lived for security purpose. Isn't it Nifi should use >refresh-token to check session validity and request new token that will renew >session if required? Regards, Hemantha
