That's not hard at all :> I do that with a MySQL database now. Here's an
examply of my authenticators:
plain:
driver=plaintext
~ public_name=PLAIN
~ server_condition = "${if eq{$3} \
~ {${lookup mysql{SELECT passwd FROM mail \
~ WHERE uname='${local_part:$2}'}{$value}fail}}{1}{0}}"
~ server_prompts= "Login::"
~ server_set_id=$2
