ClaimTypeRequirement Class

Specifies the types of required and optional claims expected to appear in the federated credential.

Namespace:  System.ServiceModel.Security.Tokens
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

'Declaration
Public Class ClaimTypeRequirement
'Usage
Dim instance As ClaimTypeRequirement

In a federated scenario, services state the requirements on incoming credentials. For example, the incoming credentials must possess a certain set of claim types. This requirement is manifested in a security policy. When a client requests a security token from a security token service (for example, CardSpace), it puts the requirements into a token request so that the security token service can issue the security token that satisfies the requirements accordingly.

The following code adds two claim type requirements to a security binding.

WSFederationHttpBinding binding = new WSFederationHttpBinding();
binding.Security.Message.ClaimTypeRequirements.Add
   (new ClaimTypeRequirement
   ("http://schemas.microsoft.com/ws/2005/05/identity/claims/EmailAddress"));
binding.Security.Message.ClaimTypeRequirements.Add
   (new ClaimTypeRequirement
   ("http://schemas.microsoft.com/ws/2005/05/identity/claims/UserName", true));

The following config file is used with the preceding code.

<bindings>
  <wsFederationHttpBinding>
    <binding name="myFederatedBinding">
      <security mode="Message">
        <message issuedTokenType="urn:oasis:names:tc:SAML:1.0:assertion">
          <claimTypeRequirements>
            <add claimType="http://schemas.microsoft.com/ws/2005/05/identity/claims/EmailAddress"
              isOptional="false" />
            <add claimType="http://schemas.microsoft.com/ws/2005/05/identity/claims/UserName"
              isOptional="true" />
          </claimTypeRequirements>
        </message>
      </security>
    </binding>
  </wsFederationHttpBinding>
</bindings>
