Sakai provides a two-tier security system designed to authorize users to perform a specified function against an entity or collection of entities. Security is implemented using AuthZGroups that provide a way to group users (membership), define a role for each of them, and define permissions associated with a particular role in that group context.
See also Permission Helpers.
Common Data Elements
The following data elements are included the AuthZGroup object:
...
Note that this interface is largely used to determine the role of a user in an externally defined group. It doesn't provide a large enough interface to move autorization outside of Sakai.
Note also that group ids for provided sites may be different than the internal Sakai representation. If corresponding realms are being maintained in Sakai (this is the typical case), then a provisional Id is also kept and is passed as the group Id when provider calls are made. Furthermore, this provided group Id may be a compound id with several external group ids concatenated using "+" as a delimiter.
