Central Authentication and Authorization Service (CAAS)

A software component that supports single sign-on and authentication for applications in the Itron back office. When users log into an application such as Advanced Metering Manager (AMM) application or any other GUI-based application, they initially log into a CAAS screen. CAAS authenticates login credentials against user role information stored in the CAAS local database for the application in question. If the credentials match a username with access, CAAS reviews the user privileges for specific application pages, then forwards that information to the application. The application then enforces the user privileges to access particular webpages or to see certain UI objects.
