Java Authentication Service Provider Interface for Containers API 1.1 1.1.1 · javax.security.auth.message.config.AuthConfigFactory

This class is used to obtain AuthConfigProvider objects that can be used to obtain authentication context configuration objects, that is, ClientAuthConfig and ServerAuthConfig objects.

Authentication context configuration objects are used to obtain authentication context objects. Authentication context objects, that is, ClientAuthContext and ServerAuthContex objects, encapsulate authentication modules. Authentication modules are pluggable components that perform security-related processing of request and response messages.

Callers do not operate on modules directly. Instead they rely on an authentication context to manage the invocation of modules. A caller obtains an authentication context by calling the getAuthContext method on a ClientAuthConfig or ServerAuthConfig obtained from an AuthConfigProvider.

The following represents a typical sequence of calls for obtaining a client authentication context, and then using it to secure a request.

AuthConfigFactory factory = AuthConfigFactory.getFactory();
AuthConfigProvider provider = factory.getConfigProvider(layer,appID,listener);
ClientAuthConfig config = provider.getClientAuthConfig(layer,appID,cbh)
String authContextID = config.getAuthContextID(messageInfo);
ClientAuthContext context = config.getAuthContext(authContextID,subject,properties);
context.secureRequest(messageInfo,subject);

A system-wide AuthConfigFactory implementation can be set by invoking setFactory, and retrieved using getFactory.

Every implementation of this abstract class must offer a public, zero argument constructor. This constructor must support the construction and registration (including self-registration) of AuthConfigProviders from a persistent declarative representation. For example, a factory implementation class could interpret the contents of a file containing a sequence of configuration entries, with one entry per AuthConfigProvider, and with each entry representing:

The fully qualified name of the provider implementation class (or null)
The list of provider initialization properties (which could be empty)

Any provider initialization properties must be specified in a form that can be passed to the provider constructor within a Map of key, value pairs, and where all keys and values within the Map are of type String.

The entry syntax must also provide for the optional inclusion of information sufficient to define a RegistrationContext. This information would only be present when the factory will register the provider. For example, each entry could provide for the inclusion of one or more RegistrationContext objects of the following form:

The message layer name (or null)
The application context identifier (or null)
The registration description (or null)

When a RegistrationContext is not included, the factory must make it convenient for the provider to self-register with the factory during the provider construction (see registerConfigProvider(AuthConfigProvider provider, ...)).

An AuthConfigFactory implementation is free to choose is own persistent declarative syntax as long as it conforms to the requirements defined by this class.

registerConfigProvider back to summary

registerConfigProvider	back to summary

This method typically constructs an instance of the provider before registering it with the factory. Factories may extend or modify the persisted registrations of existing provider instances, if those instances were registered with ClassName and properties arguments equivalent to those passed in the current call. This method employs the two argument constructor required to be supported by every implementation of the AuthConfigProvider interface, and this method must pass a null value for the factory argument of the constructor. `AuthConfigProviderImpl AuthConfigProviderImpl(Map properties, AuthConfigFactory factory)`. At most one registration may exist within the factory for a given combination of message layer and appContext. Any pre-existing registration with identical values for layer and appContext is replaced by a subsequent registration. When replacement occurs, the registration identifier, layer, and appContext identifier remain unchanged, and the AuthConfigProvider (with initialization properties) and description are replaced. Within the lifetime of its Java process, a factory must assign unique registration identifiers to registrations, and must never assign a previously used registration identifier to a registration whose message layer and or appContext identifier differ from the previous use. Programmatic registrations performed by using this method must update (according to the replacement rules described above) the persistent declarative representation of provider registrations employed by the factory constructor. When a SecurityManager is enabled, before loading the argument provider, and before making any changes to the factory, this method must confirm that the calling access control context has been granted the `providerRegistrationSecurityPermission` Parameters className:String The fully qualified name of an AuthConfigProvider implementation class (or null). Calling this method with a null value for this parameter shall cause `getConfigProvider` to return null when it is called with layer and appContext values for which the resulting registration is the best match. properties:Map<K, V> A Map object containing the initialization properties to be passed to the properties argument of the provider constructor.

A null value may be passed as an argument for this parameter, in which case the provider is registered for all configuration ids (at the indicated layers). description:String A text String describing the provider. This value may be null. Returns:String A String identifier assigned by the factory to the provider registration, and that may be used to remove the registration from the factory. Exceptions SecurityException: If the caller does not have permission to register a provider at the factory, or if the the provider construction (given a non-null `className`) or registration fails.

public abstract String registerConfigProvider(String className, Map<K, V> properties, String layer, String appContext, String description)

Registers within the factory and records within the factory's persistent declarative representation of provider registrations a provider of ServerAuthConfig and/or ClientAuthConfig objects for a message layer and application context identifier. This method typically constructs an instance of the provider before registering it with the factory. Factories may extend or modify the persisted registrations of existing provider instances, if those instances were registered with ClassName and properties arguments equivalent to those passed in the current call.

This method employs the two argument constructor required to be supported by every implementation of the AuthConfigProvider interface, and this method must pass a null value for the factory argument of the constructor. AuthConfigProviderImpl AuthConfigProviderImpl(Map properties, AuthConfigFactory factory).

Programmatic registrations performed by using this method must update (according to the replacement rules described above) the persistent declarative representation of provider registrations employed by the factory constructor.

When a SecurityManager is enabled, before loading the argument provider, and before making any changes to the factory, this method must confirm that the calling access control context has been granted the providerRegistrationSecurityPermission
