Network Deployment (Distributed operating systems), v8.0 > Secure applications and their environment > Authenticate users > Use the JAAS programming model for web authentication > Develop custom login modules for a system login configuration for JAAS > Customize application login with JAAS
Previous Step
Configure a server-side JAAS authentication and login configuration.
Step 4: Customize application login with JAAS JAX-WS
WAS supports plugging in a custom JAAS login module before or after the WAS system login module. However, WAS does not support the replacement of the WAS system login modules, which are used to create the WSCredential credential and WSPrincipal principal in the Subject. By using a custom login module, you can either make additional authentication decisions or add information to the Subject to make additional, potentially finer-grained, authorization decisions inside a Java EE application.
Customize an application login to perform an identity assertion using JAAS.
