public class JAASUserGroupCallbackImpl

JAAS based implementation of user group callback dedicated when using LocalTaskService in container such as JBoss AS. It relies on JACC api to collect information on currently logged on user when querying for tasks.
JACC exposes following named context in PolicyContext:
javax.security.auth.Subject.container
This returns Subject instance for currently authenticated user and next principals will be examined to find instances of Group and with given rolePrincipleName (by default Roles).
By default it works with JBoss Application Servers as it uses specific principal name to find the groups.
