Briefly, an IdP-first non-browser profile with attribute pull:

1. A (non-browser) client retrieves an authentication assertion from an IdP.
2. The client uses the assertion to authenticate to a CA (in a
different domain) who issues a short-lived X.509 credential.
3. The client presents the X.509 EEC to a Grid SP (in yet another
domain) who turns around and issues an attribute query to the AA.

Problem: The time-to-live of the NameIdentifier in the assertion
should match that of the X.509 cert. How is this best accomplished?

Thanks,
Tom
