OK - I just tried it again and here's what I got. Switching back to

Well, I guess it's these. -1 really is invalid and I think it
practically means that the process would get root's GID, which really
isn't a good idea.

I'll add some extra checks to make sure this can't be done with other
userdbs either..

Here's what a passwd file looks like:

marc:x:40000:12:Marc Perkel:/vhome/perkel.com/home/marc:/bin/false
test:x:40001:12::/vhome/perkel.com/home/test:/bin/false
dd:x:40002:12:Atia:/vhome/perkel.com/home/dd:/bin/false

In case the user numbers are messing things up.

BTW, thanks for looking into this.
