Abstract

Presently, most applications still use a separate authentication system for each application. It makes it diffcult for developers to synchronize the authentication system. The solution to the problem is Single Sign On. Out of various Single Sign On applications, CAS (Central Authentication System) is chosen as the Single Sign On application. LDAP used in Zimbra is used for users’ database which is to be integrated with distance learning application such as Moodle. Implementing CAS in distance learning application such as Moodle makes it easier for users in the login process in which they do not need to repetitively do it. They just
need to do it once and all the applications which support distance learning can be accessed. In addition to that, the authentication system becomes more secure because CAS makes use of HTTPS protocol which guarantees higher security because it is supported by a third-party certifcation system provided by Digicert which has been tested on a CAS server at PENS.
