Does this work for auth_passdb_lookup too, or just auth_userdb_lookup? I've
been returning a table with auth_userdb_lookup just fine. But when I try
using it with passdb (and despite being very very sure that a 'password'
key exists in the table I'm returning from auth_passdb_lookup() -- I'm
logging it one line above the return), the passdb auth fails with this log
entry:

Dec 21 23:29:22 auth-worker(7779): Info:
lua(test1 at test.com,10.20.103.32,<dSvLQuZg+uIKFGcg>):
No password returned (and no nopassword)

I guess it's not seeing the password key in the table I'm returning. If I
return a concat'd string ("password=... user=...") from
auth_passdb_lookup(), it works just fine.

I was also curious if there's a way to pass info between auth_userdb_lookup
and auth_passdb_lookup. I was trying to use a table with
auth_passdb_lookup() so I could take advantage of prefetch and thought that
if auth_passdb_lookup didn't take a table, I could stash data away and then
un-stash it in auth_userdb_lookup

Thanks!
