System.ServiceModel 4.0.0.0 System.Object This class provides two settings. You can use the property to allow the anonymous logon of clients by setting it to true. You can then avoid disclosing the client's identity to the service by setting to Anonymous. If the property is set to true (the default setting), the service can determine the Windows groups to which the client belongs.

Provides properties that describe the service credentials used for Windows authentication.

Property 4.0.0.0 System.Boolean To be added. When using Windows client credentials on a binding, by default the system does not allow anonymous access. This means that only domain or workgroup authenticated users are allowed into the system. However, in certain cases it is acceptable for anonymous, unauthenticated users to access the service. In this case you can set this property to true to allow anonymous clients to call the service. A service that enables anonymous authentication is significantly loosening the security requirements, so this setting should be used with caution. Note that this property does not apply to transport security scenarios and applies only when message security is used by the underlying binding to secure the messages. If Windows transport security is used, this property does not apply.

Gets or sets a value that indicates whether to allow anonymous users access (applies only to message-level security).

Property 4.0.0.0 System.Boolean To be added. In most scenarios, knowing which Windows groups users belong to provides useful information for authorization decisions. However, if the Windows groups are not required, setting this property to false can improve performance by avoiding a full-group claim population.

Gets or sets a value that indicates whether the Windows groups that a client belongs to are included in the security context.
