Here is what I was working with. The purpose is that I have a file in
DBDIR/authentication that contains either fully qualified addresses or
contains local_parts that are assumed to be in one of my local domains
which all share common realm/name space. An MD5-hashed password is
stored as the data value in the database.

So, I authenticate if either $2 is found on its own, or, if $2 is in
one of my local domains, I'll look up the local part of $2 by itself
and see if its in the database.

The lookups into the dbm files worked fine. However, match_domain
would *never* match one of my local domains no matter what I did,
but works fine on the same +localdomains list everywhere else in
the configuration.

I almost got to the point where it seemed like Exim (v4.60) was
clobbering the contents of $2 in some manner, which affected the second
lookup, but I can't prove that and I wasn't able to get much out
of "debug +expand".

  driver = plaintext
  public_name = PLAIN
  server_prompts = :
  server_condition = \
  "${if or { {eq {${lookup{${lc:$2}} dbm{DBDIR/authentication} {$value} {*NP*}}} {${md5:$3}}} \
             {and{{match_domain {${domain:$2}}{+localdomains}} \
                  {eq {${lookup{${local_part:${lc:$2}}} dbm{DBDIR/authentication} {$value} {*NP*}}} {${md5:$3}}}}} \
           } {yes}{no}}"
  server_set_id = $2
