The University of Cape Town (UCT) Sakai deployment has integration requirements for:
LDAP Authentication to Novell eDirectory (completed)
Novell nSure Identity Manager
The nSure vault sends us Identity information, inlcuding course membership, as SPML packets - this is implemented
Peoplesoft Student System
Aleph Library System
Some further details of UCT's integration requirements and approaches are at the UCT SakaiWiki
