Step 4: Configure ASP.NET SAML Connector as Service Provider

Step 6: Attribute Mapping

  • Attribute Mapping helps you to get attributes in your ASP.NET application received from your IdP and map them to your user attributes in application.
  • Attributes received in successful test configuration are used for attribute mapping.
  • You can refer to the below image for attribute mapping:
  • Classic ASP Single Sign-On - attribute mapping

Step 7: Integration Code

  • miniOrange SSO connector will POST a signed JWT token on this endpoint which will contain the authenticated user's info. So, first create a POST endpoint in your application.
  • Download the integration library (.dll file ) using the download option in the integration tab and add it to your project. This library contains the classes and methods with which you can verify the JWT token signature and also retrieve the user attributes from the token.
  • Use string token, string public_key function to verify the token signature.It takes token (string) and public_key (string) as parameters and returns a bool value after verification.
  • Once the verification returns true, then use getUserAttr(string token, string attr_name) function to retrieve user attributes from the token. It takes token (string) and attr_name (string) as parameters and returns attribute value (string) on success otherwise it returns an empty string.
  • Add the namespace as "Miniorange.SSO.SAML.Integrate"
  • You can refer to the example below for the integration part: Integrate intgtr= new Integrate(); // create instance for Integrate class string public_key = "1wEaPr7h34Ts+DbgPytEqwkcJlybYwOTyBVD4GryebjSIF....................";
    //Your public key displayed above.
    string token = Request.Form["token"];
    string username ="";
    if (!String.IsNullOrEmpty(token)) {
    // Verifying if the token is received from the trusted source.
    if ( intgtr.Verify(token, public_key))
    { username = intgtr.getUserAttr(token, "userid"); // retrieve the attribute value using getUserAttr method }
    } // using the received attributes from token you can create the session for that user.

Step 8: Login Setup

  • Provide the created endpoint URL for your ASP.NET application in Login Setup where you will read the JWT Token with the user attributes.
  • Click on the Save button.
  • Classic ASP Single Sign-On - login Setup

Step 9: Add SSO Link

  • Use the following URL as a link in your application from where you want to perform SSO:
  • For example you can use it as:
    <a href="https://<application-base-url>/request.aspx”>Log in</a>"

Step 10: Add SLO Link

  • Use the following URL as a link in your application from where you want to perform SLO:
  • For example you can use it as:
    <a href="https://<application-base-url>/singlelogout.aspx”>Logout</a>"
