[keycloak-user] Override "native" Keycloak providers

[Jerry Saravia]

Hello,

Disclaimer: This might be a keycloak dev mailing list question.

We’ve been using version 3.4.3 for a while now and are attempting to upgrade to 4.8 and we’ve run into some issues.

Summary: We have created our own providers with the same PROVIDER_ID as some of the built in providers. For example, PasswordCredentialProvider has a provider id of “keycloak-password” and we created our own with the same id that gets loaded after the native one. This worked because in 3.4.3 providers that were using the same id would still have their factories added to the factory map.

See this link here for 3.4.3 changes:
https://github.com/keycloak/keycloak/blob/3.4.3.Final/services/src/main/java/org/keycloak/provider/ProviderManager.java#L96-L100

These are the 4.8 changes
https://github.com/keycloak/keycloak/blob/4.8.3.Final/services/src/main/java/org/keycloak/provider/ProviderManager.java#L96-L99

In 4.8, the fully qualified class name (FQCN) is not longer used. Instead it uses the provider id and the spi name. I can no longer use the same PROVIDER_ID as the native providers to ‘override’ them, but sometimes there is code that gets the provider specifically by id. For example, in the UpdatePassword required action we have this:

PasswordCredentialProvider passwordProvider = (PasswordCredentialProvider)context.getSession().getProvider(CredentialProvider.class, PasswordCredentialProviderFactory.PROVIDER_ID);

In 3.4.3 because our provider was loaded we were able to inject into code that normally isn’t overridable. We did the same for the OIDCLoginProtocolFactory to alter some token endpoint behavior even the UpdatePassword required action itself rather than making a brand new required action that is a “second rate” because it isn’t native to Keycloak.

Is there a solution for this in 4.8.3? I see this change was made in 4.0.0.Beta1 according to some of the history.
