Yes, I do.

I thought about that, I dod, however, experience some difficultiues
while linking those two sources.


THis is what I have:

plain:
  driver = plaintext
  public_name = PLAIN
  server_condition = "${if and { \
        {!eq {$2}{}} \
        {!eq {$3}{}} \
        {eq {${md5:$3}}{${lookup mysql { \
                        select password_hash from popbox \
                        where local_part='${extract {1}{@%!}{$2}}' \
                        and domain_name='${extract {2}{@%!}{$2}}' \
                }{$value}{*:*}}} \
        }}{1}{0}}"
  server_set_id = $2




And this is what I've tried:

plain:
  driver = plaintext
  public_name = PLAIN
  server_condition = "${if and { \
        {!eq {$2}{}} \
        {!eq {$3}{}} \
        {eq {${md5:$3}}{${lookup mysql { \
                        select password_hash from popbox \
                        where local_part='${extract {1}{@%!}{$2}}' \
                        and domain_name='${extract {2}{@%!}{$2}}' \
                }{$value}{*:*}}} \
        or {if and {{eq{$2}{ph10}}{eq{$3}{secret}}}{yes}{no}}\
        }}{1}{0}}"
  server_set_id = $2




What is the correct way of connecting two different auth statements?
