Thanks so much for your response.  Unfortunately, I don't know what the
specific product is . . . However, below is the description that I do
have:

"POSIX Access Control Lists -- used to define more fine-grained
discretionary access rights for files and directories."

Given that POSIX ACLs are an access control mechanism, do they contain
any algorithms that perform authentication/password protection?



No - the ACLs are applied after authentication and identification is
complete.
They authorize the use of resources by the 'person' (meaning process)
that is attempting to access them.

	Hi Erin--
	
	The answers to these questions will be specific to the product
you are
	considering, open source or otherwise. If you could let us know
what
	specific software you're looking at, perhaps we could point you
in the
	right direction (for example, is it FreeBSD?). However, in the
general
	case, POSIX.1e ACLs are a local file system access control
mechanism
	unrelated to cryptography, and are therefore unlikely to involve
	cryptography in their implementation.


Resent to list too...
