 * Access Token
 *
 * An access token identifies a user, the user's privileges and the

 * Access Token Flags
 *
 * SMB_ATF_GUEST	Token belongs to guest user
 * SMB_ATF_ANON		Token belongs to anonymous user
 * 			and it's only good for IPC Connection.
 * SMB_ATF_POWERUSER	Token belongs to a Power User member
 * SMB_ATF_BACKUPOP	Token belongs to a Power User member
 * SMB_ATF_ADMIN	Token belongs to a Domain Admins member
