Assumptions:

• We assume the number of connected entities is less than X (<50)

Open Question:

• Do we have 1 entity endpoint (so only the whole proxy), or do we publish separate endpoints for each and every entity we have connected?

Proposed features

To be prioritised for an MVP

• Translating between SAML and OIDC

Audit trail

Search

"Proxy Wizard"

• Ability to configure entities preloaded into the proxy based on entity federation metadata

Proxy Administration

• Local accounts and roles? Or a single admin user?

Federation Management

(Primary) Entity management

• Configuration of SAML IdP
• Configuration of SAML SP
• Configuration of OIDC OP
• Configuration of OIDC RP
• Generic config management
  • Export/import of config items/entities
  • Copy/delete (copy as poor man's versioning, should it also work on groups of items)
  • Editing of entities in the GUI (common configuration items, protocol specific features)
  • Raw config edit
    • Is the GUI a facade that allows only basic configuration for beginners? If so, how do we represent more complicated valid configs that were created manually?
    • What happens if the config is broken by the user's manual changes? Display an error in the GUI and allow rollback to the previous version?
  • Apply config
  • Git config save
  • Generic post processor for configs (could be used to implement (config and Git push)
• Management of individual IDPs/Authorisation Servers/OPs and SPs/RPs/clients within the proxy (naming - "client" is more an Oauth2 term and too overloaded)
• Config checks (could also be one of post-processors)
• Versioning
• Rollback from Git (Git config restore)
• Topology graph
• Management of multiple proxy instances
• Management of proxy (related) data for individual entities
• Entity lifecycle (expressed as states in the GUI? - what is the consequence of being in a certain state?)
  
  • Draft
  • Test
  • Production
  • Support for parked entities/configs
  • Logically deleted

Other

• GUI for internal admin of the proxy (for key internal settings apart from managed services' configs)
• Federation/eduGAIN support
• Additional support for federated identity management - what specifically?
• API to access/edit service configuration/history???
• Validation of encryption and signatures of entities and their messages
• Enforcement of authentication and authorization policies - defined locally or by IdPs?
• Integration with MFA by the proxy
• Reporting and analytics - (sounds like an expansion of auditing - correctly chosen audit data and format might make this easier)
  • Statistics
  • Issues
  • Events/logs
• Step back/forward during config changes (Step-by-step wizard for adding a new entity/item)
• Dynamic updates to the configuration without requiring a full restart of the proxy service (GUI is apart from proxy services)

Managing (meta)data exchange

• Management of attribute filtering between IDPs and SPs?
• Management of mapping of attributes
• Attribute transformation rules?
• Setting of attribute values - for which entities?

Key concepts and their (alternative) names

Proxy

Entity

Configuration

IDP/Authorisation Server/OP

SP/RP/client

 - do we want to use separate "branches" for OIDC/SAML - specific names or conflate them into our unified terminology?
