5.2: Introduction to custom registries

WebSphere Application Server supports the following types of registries:

  • Local registries. Local registries are limited to single-machine or Windows NT domain-controller environments and a single application server. WebSphere Application Server does not support multiple node, multiple application servers or secure delegation when the Local registry is used as the user registry.
  • Centralized registries, which use the Lightweight Third Party Authentication (LTPA) protocol to access a supported Lightweight Directory Access Protocol (LDAP) service. Centralized registries are limited to the set of WebSphere-supported LDAP directory services. The interface for custom registries allows WebSphere applications to take advantage of new or existing registries that are not otherwise accessible.
  • Customer-defined registries, by using a WebSphere interface that facilitates access to custom registries.

For the custom-registry choice, WebSphere Application Server provides an interface that defines a set of methods that WebSphere Application Server calls to perform security operations for applications configured to use the custom registry. A developer must implement the methods in this interface by using calls to the desired registry. This layer of code allows the desired registry to be plugged into the WebSphere environment. The interface defines a very general set of methods, so it can be used to encapsulate a wide variety of registries.
