Source: SAML2 Service provider

=====================

Only deals with 'serialization' of trans

actions into the SAML SP domain
Publish SP metadata for both SPs (can also be done manually)
Publish metadata in eduGAIN via federation
(for now) Always Force AuthN (Is ForceAuthN required in the SAML spec?)
2 SPs with different ATTR policy
- affiliation only
- affiliation + identifier
saml2int
incoming attributes
eduPersonAffiliation (required)
Persistent NameID or epTID or ePPN (either, optional)
Deliver document to live up to code of conduct
Admin contact
Technical Ccontact
Support Contact
Dynamically handle incoming SAML metadata eduGAIN
Trim down this info to e.g. entityid, acs location, a hash of teh certificate
Run that at near the [admin] node, and push out well known config to nodes.
No need to deal with IdP key rollover (is part of the metadata)
Add a feature so the discovery sevice can return data for non-edugain members and act accordingly (see [SvS Proxy] Discovery Service)

RelayState

It is a requirement to keep the nodes stateless. As such a request from an RP on node 1 could return on node 2. Since no state is shared between nodes via e.g. shared DB or the likes, the state must be transported as part of the transaction. For this we use the SAML relay state, which is filled with a combination of state parametes, which are then encrypted using a symmetric mechanism using keys only known to the nodes. The keys are cycled periodically, e.g. every 10 minutes, and only teh current and 2 historic keys will be accepted. THis gives the user 30 min. to complete the authentication from the time the SP set up the request to the IdP.

The relaystate will be a tuple of the relaystate and a combination of (RP clientid, nonce, state). The latter will be encrypted using a shared key that is pushed to the nodes by the [ADMIN] git (JWE)
Keys on nodes will be cyled every 10 min.
We only allow may 3 keys (so max 30 min.)
