[Zope] Help with etcUser Folder

Hi, I'm running RedHat 6.1 with neither shadow, nor MD5 passwords, and I can't get the etcUserFolder product to work. I try creating an etcUser folder, I specify the /etc/passwd file and then it creates successfully, but no users are shown, and after specifying security levels on some other object to test it, the authentication doesn't work. It just keeps popping up the password dialog until 3 tries, and then gives an authentication error. Normal User Folders work fine. The Readme says that the cryptmodule.so might not work so I replaced it with the cryptmodule.so from my Python installation. Still no-go. Any suggestions on what I should try next? Thanks, joe
