Login module settings for Java Authentication and Authorization Service

Use this page to define the login module for a Java Authentication and Authorization Service (JAAS) login configuration.

You can define the JAAS login modules for application and system logins. To define these login modules in the administrative console, use one of the following paths:

Module class name

Specifies the class name of the given login module.

Data type: String

Proxy class name

Name of the proxy login module class.

The default login modules defined by the WebSphere product use the proxy LoginModule class, com.ibm.ws.security.common.auth.module.WSLoginModuleProxy. This proxy class loads the WAS login module with the thread context class loader and delegates all the operations to the real login module implementation. The real login module implementation is specified as the delegate option in the option configuration. The proxy class is needed because the Developer Kit application class loaders do not have visibility of the WAS product class loaders.

Data type: String

Authentication Strategy

Specifies the authentication behavior as authentication proceeds down the list of login modules.

A JAAS authentication provider supplies the authentication strategy. In JAAS, an authentication strategy is implemented through the LoginModule interface.

Data type: String
Default: Required
Range: Required, Requisite, Sufficient and Optional

Required

The LoginModule is required to succeed. If it succeeds or fails, authentication still continues to proceed down the LoginModule list for each realm.

Requisite

The LoginModule is required to succeed. If it succeeds, authentication continues down the LoginModule list in the realm entry. If it fails, control immediately returns to the application--that is, authentication does not proceed down the LoginModule list.

Sufficient

The LoginModule is not required to succeed. If it does succeed, control immediately returns to the application--again, authentication does not proceed down the LoginModule list. If it fails, authentication continues down the list.

Optional

The LoginModule is not required to succeed. If it succeeds or fails, authentication still continues to proceed down the LoginModule list.

Specify additional options by clicking Custom Properties under Additional Properties. These name and value pairs are passed to the login modules during initialization. This process is one of the mechanisms that is used to passed information to login modules.

Module order

Specifies the order in which the Java Authentication and Authorization Service (JAAS) login modules are processed.

Click Set Order to change the processing order of the login modules.
