Uh, in the README file?  The sample config file(s)?  Did you read
those?  Search for that config parameter therein?

Odd.  Is there some reason you can't serve DNS inside your organization?

Also, I'm not sure, but it might be possible to put the IP address as
the server name in $virtualDomains (but not helpful if everyone uses
the same IP)

Dunno.  You could also just keep one directory and turn on hashing
(probably level 4 for you), which would speed things up a lot.  In the
end, you have to provide a way to differentiate users into groupings
(surely there is some logic), and upon that is how vlogin can provide
different settings.  Note that there are a lot of options, all listed
in the README -- sendmail-style alias table, SQL-based grouping (with
any query you want), user-based server (and other) settings, etc.
Also, have you considered Perdition instead of Vlogin?
