=== Available User Session Data
After a user logs in from the external IDP, there's some additional user session note data that {{book.project.name}} stores that you can access.
This data can be propagated to the client requesting a login via the token or SAML assertion being passed back to it by using an appropriate client mapper.
BROKER_PROVIDER_ID::
This is the IDP alias of the broker used to perform the login.
You can use a <<fake/../../clients/protocol-mappers.adoc#_protocol-mappers, Protocol Mapper>> to propagate this information to your clients.
