Subject: Re: ntsec: changing the everyone user
Date: Mon, 15 Sep 2003 16:35:00 -0000	[thread overview]
Message-ID: <04ce01c37ba7$5b1e67a0$a500000a@chrismob> (raw)

OK. Here is an example of the way permissions leak out to "Everyone". I
create a new file, with no permissions granted to "other". Cygwin shows this
to have worked OK. Yet in actual fact there is an ACL there giving Everyone
some access rights. I usually choose not to have "Everyone" authorised to do
anything on my Windows NT/2000 boxes, using Authorised Users instead. This
way, without a valid login, you cannot get any information, including
usernames and ACLs.

How can I stop cygwin setting these ACLs?
