2. Configure ASP.NET application as service provider (SSO Module)

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

2.1: Share SAML Metadata with WSO2
  • Click on Add New IDP to configure ASP.NET Single Sign-On (SSO) with WSO2.
  • ASP.NET SAML Single Sign-On (SSO) using WSO2 as IDP - Click on Add new IDP
  • Under Service Provider Settings tab, you can either copy-paste the metadata URL on your IDP side or download the SP metadata as an XML file. Additionally, you have the choice to manually copy and paste Base URL, SP Entity ID, and ACS URL.
  • Share SAML metadata with your identity provider.
  • ASP.NET SAML Single Sign-On (SSO) using WSO2 as IDP - SP Settings Metadata
2.2: 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 - Select identity provider

There are two ways detailed below with which you can configure your SAML identity provider metadata in the module.

A] Upload metadata using the Upload IDP Metadata button:
  • If your identity provider has provided you with the metadata URL or metadata file (.xml format only), then you can simply configure the identity provider metadata in the module using the Upload IDP Metadata option.
  • You may refer to the screenshot below:
  • ASP.NET SAML Single Sign-On (SSO) using WSO2 as IDP - Upload Metadata
  • You can choose any one of the options according to the metadata format you have available.
B] Configure the identity provider metadata manually:
  • After configuring your identity provider, it will provide you with IDP Entity ID, IDP Single Sign On URL and SAML X509 Certificate fields respectively.
  • Click Save to save your IDP details.
  • ASP.NET SAML Single Sign-On (SSO) using WSO2 as IDP - SAML dll config

You have successfully configured your ASP.NET application as a service provider.

3. Testing SAML SSO
