-----------------------------------------------------------

[~exceptionfactory] I managed to setup x.509 client certificate and transferred 
client certs from my Java program to execute NiFi APIs. I have enabled all 
access policy to this x.509 user identity. The authentication is successful but 
it throws access policy error in response. Can you advise?

403 Forbidden from GET https://<>/nifi-api/flow/client-id

FYI, I can programmatically access GET https://<>/nifi-api/access end point and 
get the following response.

{"accessStatus":\{"identity":"CN=api_client, OU=dastc, O=stee, L=Singapore, 
ST=Singapore, C=SG","status":"ACTIVE","message":"Access Granted: Certificate 
authenticated."}}

> I have created oauth token using spring boot and transferred this token to 
> authorization header bearer. NiFi is configured with PS512 JWS algorithm via 
> nifi.security.user.oidc.preferred.jwsalgorithm property. But the API request 
> fails with message "nifi unable to validate the id token: signed jwt 
> rejected: another algorithm expected, or no matching key(s) found" 
> I am able to use NiFi web. Keycloak is configure to use PS512 algo for ID 
> token and access tokens.
