[keycloak-user] Is it possible to get user info from external OIDC provider and then match it against LDAP provider and get rights from there when using Keycloak?

Does anybody know if this is possible? I have setup external OIDC provider and I have setup external LDAP provider. I want the flow to be like this: 1. User has logins using OIDC provider 2. Get a token from OIDC provider and check the "sub" field against LDAP provider 3. If it exists there, then login user and add the rights from LDAP 4. If no LDAP user exists with that sub then login fails. This OIDC contains no rights or anything, just a plain info about person. Is it possible to do with Keycloak? Or it's earier to do something custom myself. ________________________________ Disclaimer: This email and its attachments might contain confidential information.
