suggestion on design new DIT

[Reza Iskandar Achmad <reza@chipset.or.id>]

Dear all,
I'm quite new in administrate OpenLDAP.
I Have been install a version of OpenLDAP to my Debian unstable.
Now I want to manage information which contain my costumer information. 
They are: Company Name, Address, Contact Person, Tel/Fax, DNS Domain 
Name dan Email Address, etc.

further, I want to use that information for my qmail, mailserver.

Now, I need a suggestion about designing Directory Information Tree that 
fit with my need.

OK, if i imagine my tree like this,

                        c=ID
                         |
                 o=MyOrganization
                         |
             +-----------+-----------+
             |                       |
        ou=customer1           ou=customer2
             |                       |
uid=shiro@customer1.co.id   mail=masumi@customer2.co.id

Note: "mail" atribute taken form qmail.schema

in "organizationalUnit" objectClass i do not find possibility to store 
costumer DNS domain name, while my customer in this situation at least 
have one DNS domain name, e.g. costumer2.co.id.

for other functions, we also need customer DNS domain name information

any suggestion for me how to store customer DNS domain name in this 
situation ?

Sorry for my bad English, I'm Indonesian :)
