I don't recall what that actually means. The login context is normally what's used to track state during login, and so there wouldn't be a principal name by then. So I'm not sure.

Assuming this is an External login handler, the ExternalAuthentication interface contains a method to get the ProfileRequestContext, and that's the root of the tree containing everything the IdP knows about the request. But I'm not sure what the original field actually meant, so I'd have to look into that. If you know offhand...
