[Zope] Shadow password

[Matt Goodall]

I would like to authenticate users from the UNIX system. Unfortunately,
my system uses shadow passwords which are not world readable so I can't
use the etcUserFolder product.

I understand the security implications of this next question but is
there any way to authenticate users but from a shadow password file?

Or is there a better way of doing things? Is there any way of using the
PAM system perhaps?

Thanks.
