--------
Is this single directory ACE (as shown by xcacls):
foobar\joe_user:(CI)R
equivalent to the combination of these 2 directory ACEs?:
foobar\joe_user:R
foobar\joe_user:(CI)(IO)R
If not how do they differ?
thanks/regards,

Notes below mainly from p248+ "Windows NT in a Nutshell":
ACL == access control list (contains ACEs)
ACE == access control entry (a single component of an ACL)
Container == a directory
Object == a file
Inherit == take on same rights as parent dir
CI == container inherit;
(directory inherit, the right applies to *this* dir AND all
*newly* created sub dirs)
OI == object inherit (*newly* created FILES below this dir inherit this ACE)
IO == "inherit only"; (modifies "OI" or "CI" on a directory; ie you never
see IO by itself); this right does *not* apply to this directory,
but it will be inherited (see example)
Example: (one ACE in a directory ACL)
SP.CG.JCI.COM\bld_mgr:(OI)(IO)C
New files below this directory will inherit this (Change) right, but this
right does not apply to this directory itself.
What makes this confusing
is that often you usually see the same right granted to the directory
in another ACE within the same ACL.
Directory ACL Example/question:
Is this single ACE:
SP.CG.JCI.COM\build:(CI)R
equivalent to the combination of these 2 ACEs?:
SP.CG.JCI.COM\build:R
SP.CG.JCI.COM\build:(CI)(IO)R
