asp.net simple implementation of single sign-on (SSO) Method _ Practical skills

The example in this article describes the asp.net simple implementation of single sign-on (SSO) method. Share to everyone for your reference, specific as follows:

Single sign-on (Sign on, SSO) is one of the more popular solutions for enterprise business integration, and SSO enables users to access all trusted applications with only one login at a time in multiple application systems

CAS (central authentication Service) is a good single sign-on framework for WEB applications (developed by Yale University) that is mainly used in Java PHP and you can study it.

Here's a simple way to implement a single sign-on:

public void Singleuserlogin (string userName) {
  //define key value
  string key=username;
  String value=convert.tostring (Cache[key]);
  if (value==null| | Value==string. Empty) {
   //define cache Expiration Time
   TimeSpan span=new TimeSpan (0,0,httpcontext.current.session.timeout,0,0);   Insert a user-related Cache value on the first landing,
    HttpContext.Current.Cache.Insert (Key,key,null,datetime.maxvalue,span, System.web.caching.cacheitempriority.notremovable,null);
    session["UserName"]=username;
    Response.Redirect ("main.aspx");
  }
  else if (Cache[key). ToString () ==key) {
    //Repeat login   Response.Write ("<mce:script type= text/javascript" ><!--   alert (' Your account has landed! '); window.location= ' login.aspx ';   --></mce:script> ");
  }
  else{
  //Cancel current session Sessions
    Session.Abandon ();
  }
　　　

Configure form mode in Web Config

<authentication mode= the "forms" >//mode value is forms for defining form validation
  <forms loginurl= "mananger/login.aspx". Aspxauth ">//users visit mananger/login.aspx page
 </forms>
</authentication>
< without landing authorization>
 <deny users= "?" />
</authorization>

I hope this article will help you to ASP.net program design.
