/*
 * Privileges
 *
 * Privileges apply to all objects and over-ride the access controls
 * in an object's security descriptor in a manner specific to each
 * privilege. Privileges are still not full defined. Privileges are
 * defined in a set structure (LUID = Locally Unique Identifier).
 *
 * The default LUID, name and display names defined on NT 4.0 are:
 * LUID Privilege Name                Display Name
 * ---- --------------                ------------
 * 0:2  SeCreateTokenPrivilege        Create a token object
 * 0:3  SeAssignPrimaryTokenPrivilege Replace a process level token
 * 0:4  SeLockMemoryPrivilege         Lock pages in memory
 * 0:5  SeIncreaseQuotaPrivilege      Increase quotas
 * 0:6  SeMachineAccountPrivilege     Add workstations to domain
 * 0:7  SeTcbPrivilege                Act as part of the operating system
 * 0:8  SeSecurityPrivilege           Manage auditing and security log
 * 0:9  SeTakeOwnershipPrivilege      Take ownership of files or other objects
 * 0:10 SeLoadDriverPrivilege         Load and unload device drivers
 * 0:11 SeSystemProfilePrivilege      Profile system performance
 * 0:12 SeSystemtimePrivilege         Change the system time
 * 0:13 SeProfileSingleProcessPrivilege  Profile single process
 * 0:14 SeIncreaseBasePriorityPrivilege  Increase scheduling priority
 * 0:15 SeCreatePagefilePrivilege     Create a pagefile
 * 0:16 SeCreatePermanentPrivilege    Create permanent shared objects
 * 0:17 SeBackupPrivilege             Back up files and directories
 * 0:18 SeRestorePrivilege            Restore files and directories
 * 0:19 SeShutdownPrivilege           Shut down the system
 * 0:20 SeDebugPrivilege              Debug programs
 * 0:21 SeAuditPrivilege              Generate security audits
 * 0:22 SeSystemEnvironmentPrivilege  Modify firmware environment values
 * 0:23 SeChangeNotifyPrivilege       Bypass traverse checking
