JAAS LOGIN IN WEBLOGIC SERVER--reference

浏览数：22 / 时间：2015年06月09日

The Java Authentication and Authorization Service (JAAS) is a standard extension to the security in the J2SE Development Kit 5.0. JAAS provides the ability to enforce access controls based on user identity. JAAS is provided in WebLogic Server as an alternative to the JNDI authentication mechanism.

WebLogic Server clients use the authentication portion of the standard JAAS only. The JAAS LoginContext provides support for the ordered execution of all configured authentication provider LoginModule instances and is responsible for the management of the completion status of each configured provider.
