SSO configuration and application

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. It includes a mechanism for ing the main logon to other applications for the login of the same user.
When a user accesses Application System 1 for the first time, the user is directed to the authentication system for Logon because the user has not yet logged on. Based on the login information provided by the user, the authentication system performs identity verification, if the verification is successful, a verification credential ticket should be returned to the user. When the user accesses another application, the ticket is carried as the authentication credential, after receiving the request, the application system sends the ticket to the authentication system for verification to check the validity of the ticket. After verification, you can access application system 2 and Application System 3 without having to log on again.
