	Java Authentication and Authorization Service (JAAS)in Java 2, Standard Edition (J2SE) 1.4
		Authentication is based on the Pluggable Authentication Modules (PAMs) with a framework to be used for both clients and servers.
		Authorization is an extension of the existing policy-based mechanism which is used to specify what permissions an application (or executing code) can and cannot do.
		JAAS authentication is performed in a pluggable fashion enabling Java applications to remain independent of the underlying authentication mechanism, and JAAS authorization augments the existing code-centric Java security architecture with user-based access controls and authentication capabilities.

	[No title]
		An authentication and authorization service may be written in Java code or interface to an existing authentication or authorization infrastructure.
		Java is the language of choice for portability between platforms, but it needs to marry its security features with those of the containing environment.
		However, to service the diverse security needs of these entities and their tasks, many Java security technologies must be used, not only at a primary level between client and server entities, but also at a secondary level, from served objects, such as EJB objects.

	Extend JAAS for class instance-level authorization
		The Java Authentication and Authorization Service (JAAS) is an extension to the Java 2 SDK.
		Unfortunately, the Java Authentication and Authorization Service (JAAS), which is part of the Java 2 platform, does not allow for class instance-level access control or special relationships.
		The Java 2 API Documentation is another excellent resource for learning about extensions to the Java 2 platform.

	Java Authentication and Authorization Service
		The Java Authentication and Authorization Service (JAAS) 1.0 is a set of Java packages that enable services to authenticate and enforce access controls upon users.
		It implements a Java version of the standard Pluggable Authentication Module (PAM) framework, and extends the access control architecture of the Java 2 Platform in a compatible fashion to support user-based authorization.
		To provide this type of access control, the Java 2 security architecture requires additional support for authentication (determining who's actually running the code), and extensions to the existing authorization components to enforce new access controls based on who was authenticated.

	MITRE - News and Events - MITRE Publications - The Edge - Summer 2002 - Authentication: Are You Who You Say You Are?
		One of the most critical security services is authentication, because it constitutes the cornerstone for additional security mechanisms such as authorization and auditing.
		System administrators have the flexibility of selecting one or more authentication technologies on the basis of their local security policy and are not required to modify each application.
		When security services are centralized, they can be leveraged to many diverse applications and reduce administrative complexity, but they can also become desirable targets and a single point of failure.

	Authentication and Authorization with WebLogic Server Security Framework 7.0
		The most common form of authentication is password-based authentication, which allows users to enter a username and password as a means of authentication when requesting access to a given resource on the server.
		In order for mutual authentication to be used as the means to authenticate the client, both client and server must present a digital certificate that indicates their identities before the connection is enabled between the two.
		The authorization and role-mapping policies can be defined by a security administrator through the use of the WebLogic Server administrative console and without having to edit XML deployment descriptors or involving a developer in order to change application business logic, and with no application redeployment required.

	IBM: Java Authentication and Authorization Service (JAAS) V1.0 for OS/390 Overview
		The Java 2 platform provides a means to enforce access controls based on where code came from and who signed it.
		These access controls are needed because of the distributed nature of the Java platform where, for example, a remote applet can be downloaded over a public network and then run locally.
		However, the Java 2 platform does not provide a way to enforce similar access controls based on who runs the code.

		Your Java class will register an instance of itself with the server, and the client will ask the server to reference that class's methods; see Figure 1.
		It can be registered with NT as a service and used to invoke another executable to create a service out of that executable.

	Resources for Java server-side developers: JAAS (2006 - Articles)
		Since 2001 when Java Authentication and Authorization Service (JAAS) was formally included in the Java 2 Platform Enterprise Edition (J2EE) 1.3 platform specification, the J2EE community has been grappling with the issue of JAAS/J2EE integration.
		Since JAAS is officially part of the J2EE platform specification, it's not unreasonable to expect that you can now leverage the JAAS framework to build portable enterprise applications that have advanced authentication and authorization requirements.
		Unfortunately, any Java architects or developers who go down this path for their applications will soon be confronted with the harsh reality: Instead of finding a landscape defined by an unified integration architecture, they'll discover a landscape littered with incompatible vendor-specific APIs and frameworks.
