<div dir="ltr"><div><div><div>We've got a similar use case - an externally managed SAML IDP is sending users our way, and we need to map them to an existing user base. There are no attributes that we can definitively use to map our users to incoming users from the external SAML IDP. We currently allow the users to authenticate on our side on their first trip, then store an association between internal/external users. This association is used on subsequent trips so that users don't have to sign in again. We've currently got this working in Picketlink, but will need to accommodate this use case with the keycloak migration coming up in the future.<br><br></div>To your question of pointing the SAML website to keycloak, it is a third party's IDP.<br><br></div>Is this sort of thing really that uncommon?

BTW, why not just point the SAML website to Keycloak? Keycloak supports<br>
