Hello everyone,

I've implemented a custom authenticator (via SPI) and in the basic form it works fine. Now when I try to extend its beavhior, adding in the pom some third party libraries, Keycloack doesn't find them.

In the official guide, reference is made to the concept of module which seems not to be supported yet. So I want to understand what is the best way to approach the problem.

This is the recap of my issue:

Version: Keycloack v19.0,1
(SPI Project) java version: 11
Goal: create a custom authenticator (via SPI)
Deployment process: simply putting the jar file into "/providers" folder
Configuration via GUI: OK
Issue: Keycloack doesn't recognize the third party libraries included in the SPI project. Without external dependencies the Authentication process works fine.
Error: ERROR [org.keycloak.services.error.KeycloakErrorHandler] (executor-thread-0) Uncaught server error: java.lang.NoClassDefFoundError: io/jsonwebtoken/Jwts

Could someone help me?

Thanks in advance
Regards
Luigi

Ok. The solution is to insert the esternal jars into the same folder of the SPI jar ("/provider" should be the name).
The conversation can be closed.
