Secure web applications may have authentication and authorization properties. The web container supports three types of authentication: basic, certificate, and form-based. The core ACLs support basic, certificate, and digest. For more information about ACL configuration, see the Sun Java System Web Server 6.1 SP7 Administrator’s Guide.
When a browser requests the main application URL, the web container collects the user authentication information (for example, user name and password) and passes it to the security service for authentication.
For J2SE web applications, Sun Java System Web Server consults the security policies (derived from the deployment descriptors) associated with the web resource to determine the security roles used to permit resource access. The web container tests the user credentials against each role to determine if it can map the user to the role.
