5.1.x JWT Authentication

[Didier Capdevielle]

Hi all,
I am testing JWT Authentication on a testing CAS Server.
Here is the URL i passed to the server : https://<server>/cas/login?service=https://<application>&token=<token>
<token> is valid on https://jwt.io/ debugger

Here is the log (cas.log) :

ERROR [org.apereo.cas.integration.pac4j.authentication.handler.support.AbstractWrapperAuthenticationHandler] - Failed to validate credentials

org.pac4j.core.exception.CredentialsException: No signature algorithm found for JWT: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

....

AND

[org.apereo.cas.token.authentication.TokenCredential@4957b789[service=org.apereo.cas.authentication.principal.SimpleWebApplicationServiceImpl@56809aec[id=https://<application>,originalUrl=https://<application>,artifactId=<null>,principal=<null>,loggedOutAlready=false,format=XML]]] of type [TokenCredential], which suggests a configuration problem.

OK. But i don't find anything about configuration, cas.properties i must change or this algorithm not found. Could anybody give some help (links, samples, ...) ?

Thanks in advance,

Best regards,

[Didier Capdevielle]

Nobody knows ?  :-(

Hi everyone,

Is someone having explanation, how to configure or example for the JWT parameters ?

## JWT authentification :
#
# cas.authn.token.name=

# cas.authn.token.principalTransformation.suffix=
# cas.authn.token.principalTransformation.caseConversion=NONE| UPPERCASE|LOWERCASE
# cas.authn.token.principalTransformation.prefix=

Thanks in advance,

Regards,
