This Sinatra app is a simplified Identity Provider for CI, QA and demo purposes.
It runs in production at https://idp.ossoapp.com and can be used by anyone.
A redis instance records email addresses and UUIDs in order to provide consistent IDs for an email address, but you can use any fake email address and any password.
Use this metadata to configure a service provider.
The login form takes any values, and will return a SAML response according to the SAML request.
