Basic architecture

eduGAIN Components

1. We assume 1 eduGAIn and 5 national feds

   - TA -> Roland testbed -  We setup the intermedats manually
   - Intermediate - Gabriels codebase includign the registration API
   - TM issuers
   - TMs
       - eduGAIN - Only national intermediates
       - National Fed Level Trustmark - Discovery, easier to resolve as compared to trust chain
       - REFEDs SirtFi - must be on national level.
       - VO membership - Independent TM
   - RPs -> Go implementation
   - OPs?
       - SSP (Marko) - Would a proxy also work with the SP side in a SAML fed?
       - Shib OP
       - Rolands OP
       - Can we proxy based on existng SAML IdPs? yes via SSP or SaToSa. - Ask Roland for readyness
       
   You may bring your own, but you are on your own, we will not support

   Do we also inject existing fed members (based on SAML metadata ) into the national federations?
   - Yes but in a different setup

   - Resolver: Most important for RPs as this will simplify RP life.

   Trust anchor based on software stack from Rolands testbed, holding 5 national federation intermediates
