Anyone running qmail+openldap+openbsd.

Dear fellows,

i am planning to build a mail server and would like to use the
following technologies :

OpenBSD 5.1 amd64
qmail-ldap-1.03-20120221
qmail-1.03

Does anybody here run an environment like ?
Are you aware of buggy stuf like openldap eating all system memory
while qmail connect/disconnect to it (slapd) ?
Is there any problem with the latest ldap patch release to be applied
to stock qmail-1.03 ?

Thanks a lot for your time and cooperation.
