dovecot - Jun 2014 - checkpassword memory limit

Hi. I am trying to authenticate dovecot from a wordpress database. I was
thinking of using the checkpassword script to start a cli php script. That php
script would then include the necessary wordpress functions, do the auth (find
the wp username from user database using the email address, and authenticate
with the user/pass), and return the result to the checkpassword script. I made
the above scripts (the php script will be used to authenticate some other
services too), and when I run them "by hand" (even with "sudo -u
dovecot ..."), it works. But, when the dovecot runs them, the php runs out
of memory. After a lot of debuging, I find out that when the dovecot starts the
checkpassword script, it makes a 250kB memory limit. But it is not enough for
the php script, it needs 14MB. I tried to put a "ulimit -v 16777216"
into the checkpassword.sh, but it doesn't work.Is there some hardcoded
limit in the dovecot itself? And if there is, could it be somehow changed?I am
using a simple D
 ebian Wheezy LAMP, and installed everything from repo. Thanks for every idea.

The whole concept sounds quite error-prone. Can't you query the database 
directly?
