The authentication uses the server's DefaultCredentials. No Service Principal Name (SPN) is specified for the server. The impersonation level is Identification, and the security level is EncryptAndSign.
When authentication succeeds, you must check the IsEncrypted and IsSigned properties to determine what security services are used by the NegotiateStream. Check the IsMutuallyAuthenticated property to determine whether mutual authentication occurred.
This method blocks until the operation completes. To prevent blocking until the operation completes, use one of the BeginAuthenticateAsServer method overloads.
