you've gone wrong at an important place here (at least, that's what i
think. it's a common enough problem, that makes me presume that ;)

{${extract{1}{:}{${lookup{$1}lsearch{/etc/virtual-domains/${domain}/passwd}{$value}{*:*}}

if your password file looks like

    username:(encrypted)password


which i suppose it does, then this extract{} stuff is most irrelevant
here. i once posted a verbose-ish explanation why it is so, you might
want to search for that. (fact is i'm too lazy to look for it myself
or write it again :) in short, don't extract. just lsearch.

wrt $domain being present, i think it's not there, you're right in
this point. authentication goes by usernames and passwords. you don't
even know (hence you can't have) the domain at the auth stage.
