Single sign on log-out method and system under cluster environment

Abstract

The invention discloses a single sign on log-out method under a cluster environment and belongs to the field of single sign-on. The method for exiting from single sign-on comprises the steps as follows: a step that an application system stores an IP address of a server, ID of session conversation of a application system end and a note mapping relation in a centralized cache; a step that an authentication central system obtains and destroys the note of an authentication end which is logged in successfully and session conversation of the authentication end; a step that the authentication central system transmits a http request to the application system via the IP address of the server; a step that the application system obtains and destroys the session conversation of the application system end according to the http request and finishes the single sign out. The invention further discloses a single sign on log-out system which is used by the single sign on log-out method under the cluster environment. The system comprises the application system, the authentication central system, a PC user end and a centralized buffer. The single sign on log-out method provided by the invention does not depend on a javascript script on a logout page, and the logout process of an account number is more accurate and efficient.

Description

technical field [0001] The invention relates to the field of single sign-on, in particular to a single sign-on exit method in a cluster environment and a single sign-on exit system used for the single sign-on exit method in the cluster environment. Background technique [0002] A session session refers to a session used to store specific user information; URL (UniformResourceLocation) refers to a character string used to describe information resources; http (HyperTextTransferProtocol) refers to a hypertext transfer protocol. [0003] Due to the increasing scale of application systems, it is usually necessary to set up an application system on one or more WEB servers. Access all application systems integrated with single sign-on; at the same time, users only need to log out once to exit all application systems. [0004] In a cluster environment, single-point logout is often achieved through the steps of receiving the logout request from the single-point server, destroying th...

Problems solved by technology

It can be seen from the above that the patent exit uses the user exit notification to realize single-point exit. This exit method usually uses javascript script to send an asynchronous request, thereby eliminating the login ticket and session session. However, if this single-point exit technology is adopted Solution, when the user logs out, the javascript on the page is not executed, and the user closes the logout notification page. This will cause some accounts that trust the website to log out, and the javascript script program cannot continue to execute. User accounts on partial trust sites are not secure
