System.ServiceModel 4.0.0.0 System.Object

This class is responsible for evaluating all policies (rules that define what a user is allowed to do), comparing the policies to claims made by a client, setting the resulting to the , and providing the authorization decision whether to allow or deny access for a given service operation for a caller.

The method is called by the indigo1 infrastructure each time an attempt to access a resource is made. The method returns true or false to allow or deny access, respectively.

The is part of the indigo2 Identity Model infrastructure. The Identity Model enables you to create custom authorization policies and custom authorization schemes. crabout how the Identity Model works, see Claims and Authorization.

## Custom Authorization

This class does not perform any authorization and allows users to access all service operations. To provide more restrictive authorization, you must create a custom authorization manager that checks custom policies. To do this, inherit from this class and override the method. Specify the instance of the derived class through the property.

In , the application can use the object to access the caller identity ().

By getting the property, which returns a object, the application can access the service (), and the operation ().

By getting the property, which returns a object, the application can access the entire request message () and perform the authorization decision accordingly.

For an example, see How To: Create a Custom AuthorizationManager for a Service.

To create custom authorization policies, implement the class. For an example, see How To: Create a Custom Authorization Policy.

To create a custom claim, use the class. For an example, see How To: Create a Custom Claim. To compare custom claims, you must compare claims, as shown in How To: Compare Claims.

crdefault Custom Authorization.

You can set the type of a custom authorization manager using the <serviceAuthorization> element in a client application configuration file.

Provides authorization access checking for service operations.

  In general, applications should override instead of this method.

  Override if the application associates or introduces a different set of policies for the resulting or provide a different policy evaluation (chaining) model.

  is generally the result from the default policy evaluation.

  Override this method to provide custom authorization decisions.

  This method can be used to make authorization decisions based on claim sets that are inferred based on incoming tokens, or added through external authorization policies. It can also make authorization decisions based on properties of the incoming message: for example, the action header.

  In this method, the application can use the parameter to access the caller identity (). By returning the object from the property, the application can access the entire request message (). By returning the object from the property, the application can access the service URL () and the operation (). With this information, the application can perform the authorization decision accordingly.

  The claims made by a user are found in the returned by the property of the AuthorizationContext. The current AuthorizationContext is returned by the property of the class.

  Checks authorization for the given operation context based on default policy evaluation.

  true if access is granted; otherwise, false. The default is true.

- Method

  System.Collections.ObjectModel.ReadOnlyCollection<System.IdentityModel.Policy.IAuthorizationPolicy> `` To be added.

  The indigo1 implementation provides a default set of authorization policies. These include the primary token that contains the credentials of the requester and all supporting tokens, transport tokens, and external policies if specified.

  You can override this implementation and provide a different set of policies.

  Gets the set of policies that participate in policy evaluation.
