[keycloak-user] Verification of Access Token failed

Hi all, I am struggling with access token verification. So here is what I am doing (using Keycloak 4.5): 1. Generate an offline auth code from Client A. 2. Generate a refresh token from Client A. 3. Generate an access token from Client A. This token has an *ES256* Signatur. When using this token, I got an error from my Spring Boot application, that the used public key was not available: "Didn't find publicKey for specified kid". I set the public-key-cache-ttl to 1 sec and the log level to debug and could see, that only one pubilc key was retrieved for my configured Client: "Realm public keys successfully retrieved for client xxxxxxxxxx. New kids: [xxxxx]". As I could see in the realm settings, the key was created using *RS256*. When I force the Client A to just use RS256 signature by setting the "Access Token Signature Algorithm", then it works fine. But I wonder, how I could also use other signature algorithms!? Release notes are stating, that both (and more) algorithms are supported. Thanks for your help! Regards Tim
