On vacation at present.

From email to Tom : AttributeMapper config via AttributeResolver, DataConnector tests and logging, injecting Velocity into RDBMS and Ldap DC.

Tom AI : Ask for more details about the "Spring inside V2" code issue.

Tom AI : Ask Rod to investigate FilesystemResource + ClasspathResource -> SomethingResource which understands "classpath:* and "file:*" semantics ala everything else as part of Resource review.

Scott

Completed first batch of authentication work:

  • Context design
  • Configuration and selection of flows
  • SSO via active results pulled from session (session itself is TBD)
  • Implemented and tested flows for IP authn, asserted RemoteUser or header, and form/basic-auth to JAAS
  • Successful integration of nested subflows for Authentication into MVC profile testbed
  • Explored error handling a bit
  • Handling of AuthnContext, including non-exact matching

Documented some identified issues with SWF (Spring and Web Flow Technical Issues), primarily the known issue of non-serializability.

Aside from polish, and those issues, an outstanding area of concern is how the SAML 2 SSO handler will figure out how to populate the AuthnContext in the response. Might need some adjusting of the design at that point.

Also defined a subflow integration point for subject canonicalization and tested "simple" implementation.

Planning to look at Session layer next, along with supporting client-side storage service, which led to DataSealer enhancement work.

DataSealer should be used anywhere the IdP needs to MAC and/or encrypt data for its own use. Produces base-64 blobs that are now GCM-encrypted, which builds in a MAC. Each blob encodes a cleartext key alias that's part of the MAC so we can add new keys but still recover old blobs if the original key is left in the keystore.

Thinking down the road we might be able to generate and store fresh keys on a scheduled basis and have it auto-rotate.

Tom

Jetty, java-shib-testbed, idp-distribution, idp-war, SWF, Velocity wiring, external flows and templates, idp-conf, Version.java (sigh), aacli.sh and version.sh, refactor idp-core, git.

Questions (apologies in advance, if we run out of time) :

What is current state of thought regarding name format semantics for an EntityID, like NameID ?

Why are target (redirect) URLs not in the SAML spec ? e.g. why are query strings "required" in addition to assertions
