[keycloak-user] Keycloak does not found SPI User Storage provider

[Alfonso Vidal García]

Good morning,


I have configured a Spring Boot project with connection to Keycloak, and also I want to install a Custom SPI User Provider external to Keycloak.

I did all the steps to do the Provider and ProviderFactory, and also the file in META-INF/services, and when I try to deploy on Wildfly to connect with Keycloak, fails,

I try to search in all internet about solutions about that, and I am blocked, so If you could tell if anything is missing.
