Implementation of CAS Server as Authentication Protocol on Single Sign-On (SSO) Network With PHP Programming

Web application development demanding user applications to manage users and passwords application system as well indirectly, so as not to be abused by not authorized parties. User account security methods have been tried to solve the problem. Including by implementing authentication service on Single Sign On (SSO) network, applying Server Radius as captive portal authentication, and by building a CAS Server as authentication Center and with each others methods by programming languages variety. This research was conducted by means of experimenting to make a CAS Server as authentication center that built with PHP programming language. Aside from that, this paper also describes how to test the performance of CAS Server by using tools hacking application (Apache Banch). The tools hacking application can run on Linux Ubuntu operating system. Whereas the methods used in this testing is black box methods (functional testing). The results showed that CAS Servers have been built as a authentication center in Single Sign On (SSO) network was able to respond requests maximum for users as much as 4.490.000 request, for a total time of request 5.406,568 ms (5 seconds). Thus CAS Server that has been built is very suitable to handle the user request is less than 4.490.000 request.
