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


ASP.NET SAML 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. To check the other features we provide, click here.

Platform Support: The ASP.NET SAML SSO module supports ASP.NET 3.5 and above frameworks.

Steps to configure ASP.NET Single Sign-On (SSO) using WSO2 as IDP

1. Configure WSO2 as identity provider

  • You need to send your SP metadata to identity provider, WSO2. For SP metadata, use the SP metadata URL or download the SP metadata as a .xml file and upload it at your IdP end. You can find both these options under the Service Provider Settings tab.
  • There are two ways detailed below with which you can get the SAML SP metadata to configure onto your identity provider end.
  • A] Using SAML metadata URL or metadata file:
    • Under Service Provider Settings you can find the metadata URL as well as the option to download the SAML metadata.
    • Copy metadata URL or download the metadata file to configure the same on your identity provider end.
    • You may refer to the screenshot below:
    • ASP.NET SAML Single Sign-On (SSO) using WSO2 as IDP - Copy Downloaded Metadata
    B] Uploading metadata manually:
    • From the Service Provider Settings section, you can manually copy the service provider metadata like SP Entity ID, ACS URL, Single Logout URL and share it with your identity provider for configuration.
    • You may refer to the screenshot below:

2. Configure ASP.NET application as service provider

Note: After installation of the plugin, we need to setup the trust between your ASP.NET application and your WSO2 account. SAML metadata is shared with WSO2 so they can update their inbuilt configuration to support Single Sign-On.

Import WSO2 SAML metadata

  • Select WSO2 from the list of identity providers shown below.
  • ASP.NET SAML Single Sign-On (SSO) using WSO2 as IDP - search idp

    • Click Save to save your IDP details.
