[Building Sakai] Sakai role system 101

[Kurosch Petzold]

Hello,

is there any detailed documentation available for the role system used in
Sakai. I know it is Role-Based Access Control (RBAC) but there is hardly
any information about any specifics how it is implemented or whether it
uses RBAC96, NIST model, another model or a custom model.

I would really appreciate any help as I need to document how the complete
role system works for my thesis and it would help us expand our IT
proceedings documentation.

Best regards,
Kurosch
