Entitlements managed through the Entitlements Service driver are called “role-based entitlements”, or RBEs, because they are granted to users who are members of, or have a role in, an entitlement policy. Only the Entitlements Service driver uses role-based entitlements and entitlement policies. The two other entitlement agents (roles based provisioning and workflow-based provisioning through the User Application) use their own methods for assigning entitlements to users.
The role-based entitlement functionality in iManager lets you manage the entitlement policies used by the Entitlements Service driver.
