Represents the security context of a remote party. On the client, represents the service identity and, on the service, represents the client identity.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The data is part of the SecurityMessageProperty for a message.
Use this class to obtain information about a remote security context at runtime. A security context is created when a client is successfully authenticated and authorized to access a method. When a message is successfully authenticated and authorized, the security information from the client and for the current service instance can be obtained from an instance of this class.
Parsing a ClaimSet
A common use of the class is to retrieve the current set of claims for the purpose of identifying or authorizing a client when accessing a method. The ClaimSet class contains a collection of Claim objects, and each can be parsed to determine whether a specific claim is present. If the specified claim is provided, authorization can be granted. This functionality is provided by overriding the CheckAccessCore method of the ServiceAuthorizationManager class. For a complete example, see the Authorization Policy Sample.
Cookie Mode and IsAuthenticated
Note that under some circumstances, the IsAuthenticated property of the IIdentity interface returns true even if the remote client is authenticated as an anonymous user. (The PrimaryIdentity property returns an implementation of the IIdentity interface.) The following circumstances must be true for this to occur:
The service uses Windows authentication.
The service allows anonymous logons.
The binding is a customBinding Element.
The custom binding includes a <security> element.
The <security> element includes a secureConversationBootstrap element with the requireSecurityContextCancellation attribute set to false.
The following example uses the class to provide information about the current security context. The code creates an instance of the StreamWriter class to write the information to a file.
The following example shows an implementation of the CheckAccessCore method that uses the to parse a set of claims.
