# DESCRIPTION:
#	Verify  1) Illegal options to chmod should fail.
#		2) Delete all the ACE will lead to fail.
#		3) Add ACE exceed 1024 will cause to fail.
#
# STRATEGY:
#	1. Loop root and non-root users
#	2. Verify all kinds of illegal option will lead to chmod failed.
#	3. Verify 'chmod A0-' will fail when try to delete all the ACE.
#	4. Verify 'chmod A+' will succeed when the ACE number exceed 1024.
