Right, there's two halves to it, getting to the tree, and then what's in the tree.

Leaving getting to it out of the way, the principal name in the LoginContext in V2 is, like I thought, after the login happens. It's the identity a login handler returns as the result of the login process.

I'd have to know the specific need for the data to understand the best place to point somebody now. The best "single" answer to this would be the PRC->SubjectContext->getPrincipalName() but that's only there "after" all of the authentication sequence runs.
