[anlex N]

Hello Teacher!
I value your feedback very much

Nice to meet you. My name is anlex N <https://github.com/anlexN>.

I am a verified google maintainer of popular open source projects.

I am reviewing POSIX accounts, permission, and security
<https://cygwin.com/cygwin-ug-net/ntsec.html>. Today is 2024-07-06, This
doc introduces rfc 2307, but rfc 2307 has been legacy for a very long time.

Have Cygwin source code used tech from rfc 2307? When does Cygwin team
update this docs?
