| dc.description.abstract | Single Sign-On (SSO) is a property of access control of multiple related-but-independent software systems. With this property a user logs in once and gains access to all systems without being prompted to log in again at each of them. This research develops a system that provides Single Sign-On service that can be done through a web application and proxy. Authentication through a web application is made by the OAuth 2.0 protocol which centralizes the system without spreading authentication credentials to all applications. All web applications are authenticated using a token. Proxy authentication is performed with three types of connections between the proxy and SSO server. The connections are tested using a database connection, web service, and local file access. Speed connection is tested when receiving requests from users. From the test results, the best connection between the proxy and SSO Server is obtained by using local file which is helped with rsync. This SSO system still experiences problems when it is used on networks that use NAT and when a user uses Internet Explorer browser. | en |
