SAFIRE is in the process of transitioning, both in architecture (from full-mesh to hub-and-spoke) and governance (from the SCA to TENET). The purpose of this post is to provide more detail on the transitional arrangements.
1. Change freeze
There is a change freeze in force for the existing full-mesh federation. No new metadata will be added to the existing SAFIRE metadata aggregate and only emergency changes will be made. Should such changes be required, please communicate these to both TENET and the SCA.
2. Parallel operations
Both the existing full-mesh and the new hub-and-spoke federations will operate in parallel for a number of months, until such time as all existing, functional identity- and service providers have migrated. It is possible (perhaps likely) that there are some stale providers in the existing metadata, so some discretion will be used in determining the exact date at which parallel operations cease.
This date has been determined to be 30 June 2017: Shortly after midnight on 1 July 2017, all remaining identity providers in the full-mesh federation will expire. (Some IdPs who are part-way through the transition may expire sooner than this - individual IdPs have been contacted with details.)
Between 1 July and 31 July, service providers who have not completed the transition may still be able to access SAFIRE IdPs via a click-through warning. However this is not supported, and the functionality will be removed on 31 July.
After 31 July, the old full-mesh federation is no longer expected to work and may be dismantled at any point.
3. Order of transition
The intent is to migrate existing identity providers first, then to migrate existing service providers. However, in some instances organisations act as both identity- and service- providers, and so it may make sense to relax this slightly.
Caveat: whilst transitional arrangements exist to ensure IdPs that have transitioned remain available in the full-mesh federations, no such arrangements exist for SPs. Thus once an SP is migrated, it will become inaccessible to IdPs who have not yet completed the transition.
New services and identity providers may only join the hub-and-spoke federation, and will only have their metadata added after the transition from full-mesh has been completed. New providers are being taken on concomitantly.
4. Individual transitions
At the appropriate time, the Project Director will contact individual entities to begin the process of transition. This may be broken up into a number of phases to deal with the logistical.
4.1 Participation agreement
As a first step, transitioning entities will need to complete and sign the SAFIRE Participation Agreement. This document outlines the various roles and responsibilities of the parties involved, and forms the basis of the trust relationship.
We anticipate that many organisations will need to put this document through their internal processes, and this may take time. In addition, these processes may slow or stall over the December/January period. For this reason, we invite all existing participants to begin this step immediately.
Please sign and scan (or electronically sign) a copy of the Participation Agreement and email it to us. TENET is happy to accept scanned documents and/or electronic signatures, and will normally return an electronically signed copy to you.
Should your processes require original handwritten signatures, please post or courier two copies of the signed agreement to TENET’s offices (one will ultimately be returned to you by post countersigned by TENET). In addition, to counteract postal delays, please send a scanned copy as above.
Queries about the agreement can be directed to the same place.
4.2 Metadata registry take-on
Existing metadata from the full-mesh federation will not be migrated to the hub-and-spoke federation. Instead, entities will be asked to supply new metadata for inclusion in the Federation registry. The reason for this is that the majority of metadata in the existing federation does not comply with the MRPS and other requirements.
Note that the technical transition does not need to be complete in order to add metadata into the new Federation Registry. In fact it might be desirable to do this sooner rather than later, since it will aid testing of the new technology.
To aid with preparing metadata, a SAML2 metadata validator is available at https://validator.safire.ac.za/. Whilst still in development, this applies very similar rules to SAFIRE’s metadata aggregator and tries to check the technical requirements.
The new requirements for identity providers are documented. Identity providers will need to complete the SAML2 IdP Registration Request form. The completed form can be emailed together with the proposed metadata to c2FmaXJlQHRlbmV0LmFjLnph .
The new requirements for service providers are documented. In particular, these three were not previously enforced and may require some thought/effort:
Metadata that does not contain the mandatory elements will not be added to the registry. We will work with you to ensure you have valid metadata.
4.3 Provider configuration
Once the hub-and-spoke federation is technically operational, entities will need to reconfigure their providers to consume the new Federation’s metadata. It is recommended that you use a dynamic/automated metadata provider (Shibboleth, SimpleSAMLphp) to do this and you refresh the metadata approximately every four hours.
IdPs may also need to review the required and supported attributes to ensure that they will release the right information.
SPs may need to review their access control policies, particularly if they are based on attributes sent.
Once the above steps are complete, the entity should test that things are working correctly. Identity providers can use the Test Service Provider for this purpose.
4.5 Removal from full-mesh
Once the entity confirms that everything is working and that they have no remaining dependencies in the full-mesh federation, they can remove the full mesh configuration from their provider.
5. Logo & Branding
To-date the costs of SAFIRE have been largely borne by the SCA and TENET. This is an interim arrangement, and it is expected that going forward costs will be recovered from identity provider (but not service providers). Please review section 3. of the Participation Agreement for details.
7. New providers
Questions and updates
Its likely that, in preparing this document, we’ve overlooked or not clearly stated something. Thus if you have specific questions about how things will work, please feel free to ask. We’ll keep this document updated as this happens, so please check back here too.
