Authorization is the act of determining that a person is entitled to access a resource in question.
After an end user is authenticated, a system can then make an informed decision as to whether that end user should be allowed to access the resource they are requesting.
Current Authorization Services
Apollo is a centralized, mainframe-based authorization and group membership repository. It allows developers to set up group membership and authorization schema for their applications.
The OHS Contacts System (OHSC) is a tool used by central offices to identify individuals in campus departments that are responsible for specific business and technical roles.
SailPoint IdentityIQ (IIQ) provides group and role management functionality which allows an organization to manage application authorizations more efficiently by treating a collection of users who need the same type of access as a unit. One or more authorizations can be associated with the role and users can be assigned to that role either by request or automatically based on an attribute on the user.
