Welcome to Sustainsys.Saml2

The Sustainsys.Saml2 library adds SAML2P support to ASP.NET web sites, allowing the web site to act as a SAML2 Service Provider (SP). The library was previously named Kentor.AuthServices. Sustainsys.Saml2 is open sourced and contributions are welcome, please see contributing guidelines for info on coding standards etc.

Using Sustainsys.Saml2

Using the Sustainsys.Saml2 library to add SAML2P support into your ASP.NET web applications is a two-step process:

  1. Reference the Nuget package
  2. Provide the necessary configuration information

The exact nature of these steps depends on the ASP.NET integration you’re after. See Getting Started for all the details.
