Acme identity provider

Two custom authorization servers on this one hostname:
  https://f16-other-idp.huntland.abiusx.com/oauth2/guest   Guest sign-up is open. Anyone may create an account and sign in here.
  https://f16-other-idp.huntland.abiusx.com/oauth2/admin   Administrators only. This login server issues tokens to the Administrators group.

Each has its own signing key, discovery document, directory and access policy.
