[keycloak-user] Integrate with WebLogic?

Hi I'm wondering what I have to do to integrate with WebLogic. Am looking to replace OAM with Keycloak but looks like there is no WebLogic support out of the box. Do I just have to implement an Identity Asserter for WebLogic and I'm good to go or do I need to implement anything on Keycloak's end as well? Thanks -- Thomas Isaksen
