need advice on ldap setup

[BsD JuNkiE]

I am setting up my first qmail-ldap system and would like to know if the 
ldap layout for my database is ok.
I  intend to use phpQLADMIN 2.0.8 to manage qmail-ldap and the ldap 
server is a clean openldap 2.1.12 install.

dn:dc=dev-null.homeunix, dc=org
objectclass: top
objectclass: organizationalUnit

Will the above work?  Is PhPQLADMIN setup correctly above to work, i 
read you had to give phpqladmin its own directory and define the 
objectclasses: phpqladminconfig and phpqladminbranch ...so is this correct?

Currently i will only have one doamin, but i might need to have 2 
virtuals latter with 2 mailing lists.

Any guidance, suggestions would be greatly appreciated!

Have a fantastic day!

Thanks,
