[keycloak-dev] Override "native" Keycloak providers

Wed Jun 5 06:26:17 EDT 2019

Hi,

I also wanted to override the default SAMLProtocolFactory with my class with the same provider id as Thomas mentioned.
In my case, it has been successful in replacing the native provider with the same provider id by using the Keycloak Deployer [1]. I confirmed it works with keycloak version 4.3.0.Final, 4.8.3.Final and 6.0.1.

The deployment approach is as follows. I think it's a straightforward way than deployment as a module. +Bonus: Hot deployment works !!

- Create "jboss-deployment-structure.xml" and place under the "META-INF" directory in your JAR or EAR which contains your classes.
- Deploy JAR or EAR by placing it in the "$KEYCLOAK_HOME/standalone/deployments/" directory.

Hello Jerry,

I encountered a similar problem with Keycloak 4.x when I needed to implement my own SamlProtocolFactory to customize the SAML Message handling.
See: http://lists.jboss.org/pipermail/keycloak-dev/2019-February/011745.html<https://nam02.safelinks.protection.outlook.com/?url=http%3A%2F%2Flists.jboss.org%2Fpipermail%2Fkeycloak-dev%2F2019-February%2F011745.html&data=02%7C01%7Cjerry.saravia%40virginpulse.com%7C40d6fd71af6b4998c21a08d6b302ceed%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636893221988678776&sdata=JRszK70Y260c5Lvbra19Qp4E%2B9FswzPwPMJRQb8t5G4%3D&reserved=0>
The only way I could get this to work was to add my custom extension jar to the module.xml of the keycloak-services module,
see the link for details.

It's by far not the best solution, but at least it works.

Cheers,
Thomas

Hello,

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<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkeycloak%2Fkeycloak%2Fblob%2F3.4.3.Final%2Fservices%2Fsrc%2Fmain%2Fjava%2Forg%2Fkeycloak%2Fprovider%2FProviderManager.java%23L96-L100&data=02%7C01%7Cjerry.saravia%40virginpulse.com%7C40d6fd71af6b4998c21a08d6b302ceed%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636893221988678776&sdata=0pjRiO7IuJLBc7XxS%2F2UOwZKDDL4RGbu3yHPJO%2FFG5U%3D&reserved=0>

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<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkeycloak%2Fkeycloak%2Fblob%2F4.8.3.Final%2Fservices%2Fsrc%2Fmain%2Fjava%2Forg%2Fkeycloak%2Fprovider%2FProviderManager.java%23L96-L99&data=02%7C01%7Cjerry.saravia%40virginpulse.com%7C40d6fd71af6b4998c21a08d6b302ceed%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636893221988688789&sdata=I5hMBZLoQsSFqEakuWb6uSTtuAGOAUSfeQ%2B4CIOwPZY%3D&reserved=0>

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.
