First, what is single sign-on. Single Sign On (SSO) is one of the most popular solutions for enterprise business integration. SSO is defined in multiple application systems. Users only need to log on once to access all mutually trusted application systems.
The CAS logon system has two roles. One is a Web application that provides the logon service, logon page, and client verification.
