推荐答案

您似乎缺少了SAM在的web.config 。

You seem to lack the SAM in web.config.

  <httpModules>
         <add name="SessionAuthenticationModule" 
              type="Microsoft.IdentityModel.Web.SessionAuthenticationModule, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
  </httpModules>
