I think your going to find, that for virtual domains, you'll need
virtual users... So ether you have 5 passwd files, or you use a
database backend. Using the Unix /etc/passwd is not virtual users, and
you have no way of telling it, which user is which domain.
Do yourself a favour, and use a database backend, otherwise, use a
separate passwd file (hash file?) for each domain.

Seeing as I don't use the flat file's, I can't offer any more help,
but I'm sure the wiki has more info.
