Central Authentication Registry A Web Services Project


The name CAR  refers to a software package that implements the sign- on protocol. The Central Authentication Registry (CAR) is a single sign-on protocol for the web. Its purpose is to permit a user to log into multiple applications simultaneously and automatically. It also allows web applications to authenticate users without gaining access to a user’s security credentials, such as a password.REGISTRY-A-WEB-SERVICES-PROJECT


The name CAR also refers to a software package that implements this protocol. Companies face several problems in order to distribute the sign in parameters to every plausible person. Today’s companies have multiple applications and departments accessed by several employees. IN order to make an application accessible the employee is required, however, the sign –in parameters for each application vary and distributing these parameters to all the employees is a difficult task. 

The users face similar problems in case the employee doesn’t provide them with an appropriate sign-in or the wrong parameters to sign –in an application. These problems have been identified and the appropriate solutions have been programmed in CAR software package. 


This project should be implemented using Web Services or WCF technology only. The biggest organizations the User credentials will be centralized in a registry for the access of different applications the Authentication details will be retrieved from the registry (usually Lotus Notes Domino or Windows Active Directory) and based on Credentials the applications access role will be provided. 

The system can be accessed over the internet and makes the overall employee login access management easier and flexible. The user information can be stored in centralized registry which can be maintained by the system. This enhances the security control as the user’s information and date is stored in the server machine. Only registered users can access the particular application since authentication is provided.
