1. 1. The addon reads some data that tells it stuff like:
   2. That the site is an RP for OpenID, IMI and SAML protocols (unusually it does not support username/password!)
   3. The list of attributes that the site wishes to receive and for each attribute the list of authorities that the RP trusts. In our case the site is going to request only a non-correlateable identifier (aka an IMI "PPID", OpenID "directed" identity, SAML "persistent" NameID) and that it trusts only Yahoo, AOL, Google, as well as Facebook, Equifax, Citigroup, Silicon Wave, Acxiom, and InCommon IdPs to issue this attribute
2. The add-on displays a login window.
   1. It prominently shows the following accounts that could be used immediately (because Alice has these accounts and the NIH site accepts these accounts):
