Logging:

Sakai should log the login of users and record the way in which the user authenticated (awp9 logged in at TIMESTAMP via CAS). Sakai should log ticket validation failure, ideally logging the raw validation failure response / exceptional condition encountered. Sakai should intelligently log SSL / cert problems on ticket validation when encountered.
Performance Concerns:

titleMain Success Scenario
borderStyledashed

Deployer successfully configures Sakai instance such that: End user visits Sakai. Sakai offers a "Log in via CAS" button. User clicks button, authenticates to CAS, CAS redirects back to Sakai. Sakai validates service ticket, establishes user session, context, etc., user is authenticated to and logged into and begins using Sakai.

AFAIK, Sakai already supports CAS authn. I enter this use case for two purposes: 1) there is potential to go beyond CAS authn to Sakai being merely possible, to make it a productized, polished, feature of the product. Enough schools need to do this that it seems worth producing the polished guide to doing it well.

2) Even if already implemented, this is an important use case to continue to consider as Sakai develops. Enterprise integration with Sakai is important to enabling other integrations.
