[keycloak-user] KeyCloak multi-tenancy and third parties

Hi, We are using KeyCloak with multi-tenancy, each realm represents a customer, in addition we are using a third parties (e.g. bloomfire and litmos) were we don't have much control over the code. Those parties support SAML 2, however when a user access the third party how can KeyCloak know its tenant ? since we can't change the third parties, is it possible to somehow first ask the user its tenant and then redirect him to the login page ? Any advice will be appreciated. Thanks, Haim. The information contained in this message is proprietary to the sender, protected from disclosure, and may be privileged.
