All Implemented Interfaces:

public class PrincipalPermission
extends ClientPermission

PrincipalPermission represents an access limitation to the private resource for a particular principal. This permission cannot be granted in java policy file and mostly is used in runtime.

For example this permission is checked in the scheduler when the user tries to remove the job to allow users remove only their own jobs.

Then user is authenticated in JAAS it automatically has all PrincipalPermissions of those principal it associated with. For example when a user named "Bob" is authenticated and it is a member of group "users" it will have 2 PrincipalPermission: PrincipalPermission(UserPrincipal("Bob")) and PrincipalPermission(GroupPrincipal("users")).

Then in the code if an action is limited to PrincipalPermission(UserPrincipal("Jon")) Bob cannot access it. If it's limited to PrincipalPermission(GroupPrincipal("Bob")) or PrincipalPermission(GroupPrincipal("users")) or PrincipalPermission(none) it is authorized to execute it.
