For impersonation to take place, the request must have a Windows identity. Without a Windows identity, it is not possible to extend the rights of the service. This makes sense because if the client doesn t have a Windows identity, there are no additional rights that could be conveyed to the service.

Impersonation within WCF can take place at two different levels. Transport impersonation means that the credentials used to secure the transport layer are provided to the service to control access. The most common types of impersonation at the transport layer are Identify and Impersonate. The None and Anonymous levels are not recommended for use and are not supported by many transport protocols. The Delegate level is a very powerful option and should be used only when the client and the service are both trusted applications. For the service to use Impersonate or Delegate levels, it needs to have the SetImpersonatePrivilege privilege set. Although any user can be configured to have this privilege, by default, it is available

only to members of the Administrators group or accounts that have the Service SID (Local System, Local Service, or Network Service). As was already mentioned, the transport choice affects the ability to perform impersonation. For example, if named pipes are used as the transport, impersonation and delegation are not supported. If HTTP is used as the transport, the limitations on impersonation become related to the authentication scheme. Table 8-8 shows the authentication schemes and the different levels of impersonation that are allowed.

Authentication Scheme Anonymous Basic Digest NTLM Kerberos
The second technique used to implement impersonation involves the use of SOAP. Keep in mind the requirement that a Windows identity must be available to the service, so any request needs to have information about the identity included in the metadata associated with the request. SOAP accomplishes this by using one of two methods, cached token impersonation and Service-for-User (S4U) impersonation. Cached Token Impersonation When an incoming call is processed, a token is requested from the Security Support Provider Interface (SSPI) or Kerberos authenticator. This is a token associated with a Windows identity and is then cached at the service so that future requests from the same user can be processed more efficiently. Cached token impersonation is available to some types of bindings. wsHttpBinding, wsDualHttpBinding, and netTcpBinding when the client presents a Windows credential. basicHttpBinding and basicHttpSecurityBinding when the security mode is set to TransportWithMessageCredentials. In this case, the credentials provided must map to a Windows identity. Any custom binding when a Windows client credential is presented and requireCancellation is set to true. The requireCancellation attribute ensures that the validation of the identity is performed with every request, enabling the caller s information to be populated into the Windows identity element. Any custom binding when a UserName client credential is presented and can be mapped to a Windows user. Again, the requireCancellation attribute must be set to true, and the credentials must use a provider that validates against a Windows domain.
Lesson 2: Authorization and Impersonation
Service-for-User (S4U) Impersonation The idea behind S4U impersonation is that the token retrieved from Kerberos contains information about the type of impersonation that can be performed the token that arrives at the service is used directly to provide the required level of impersonation. The types of bindings that can use this impersonation are: wsHttpBinding, wsDualHttpBinding, and netTcpBinding when the client presents a certificate credential that can be mapped to a Windows identity. A custom binding when a Windows client credential is presented and requireCancellation is set to false. This last requirement enables the token information to be flowed from the client to the service. A custom binding requiring a secure conversation and providing UserName credentials. Again, requireCancellation must be set to false.
