ASP.NET SAML Single Sign-On (SSO) Using WSO2 As IDP


ASP.NET SAML SP Single Sign-On (SSO) module gives the ability to enable SAML Single Sign-On for your ASP.NET applications. Using Single Sign-On you can use only one password to access your ASP.NET application and services. Our module is compatible with all the SAML compliant Identity providers. Here we will go through a step-by-step guide to configure Single Sign-On (SSO) between ASP.NET and WSO2 considering WSO2 as IdP.

Pre-requisites : Download And Installation

  • Download miniOrange ASP.NET SAML 2.0 Module.
  • To set up the module, extract the file asp.net-saml-sso-module-xxx.zip. You will find a DLL named miniorange-saml-sso.dll, a configuration file named saml.config and an integration.md file which contains steps for adding the module into your application.
  • Add miniorange-saml-sso.dll into your bin folder (where other DLL files for your application exist).
  • Register minorangesamlsso module in your application according to the steps provided in the file named integration.md.
  • Add the provided configuration file saml.config in the root directory of your application.
  • After integration, open your browser and browse the connector dashboard with the URL below:
    https://<your-application-base-url>/?ssoaction=config
  • If the registration page or login page pops up, you have successfully added the miniOrange SAML SSO connector to your application.
  • saml dll register
  • Register or log in with your account by clicking the Register button to configure the module.
