Error while adding a custom token handler

Question

Hi there,

I've read a load of examples and threads with regards to add a custom token handler.

However, I have a problem with configuration which in web.config.

  <microsoft.identityModel>
    <service>
      <securityTokenHandlers>
        <!--<remove type="Microsoft.IdentityModel.Tokens.UserNameSecurityTokenHandler, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />-->
        <remove type="Microsoft.IdentityModel.Tokens.WindowsUserNameSecurityTokenHandler, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add type="CustomUserNameSecurityTokenHandler"/>
      </securityTokenHandlers>
    </service>
  </microsoft.identityModel>

With this configuration, I got following exception ...

ID0006: The input string parameter is either null or empty.
Parameter name: value 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Thanks!

I get the same error. Have a solution for me?

You are getting this error probably because your microsoft.identityModel section is missing the following element:

      <federatedAuthentication>
          <wsFederation passiveRedirectEnabled="true"
                        issuer="your identity provider URL"
                        realm="your relaying party URL"
                        requireHttps="true" />
      </federatedAuthentication>
