Problem adding ldif.

["Jim Greene" <jwgreene@megalink.net>]

Hello,
    I have added the following ldif with no problems:
 dn: ou=isp,dc=domain,dc=net
objectClass: organizationalUnit
ou: isp
description: hosting root

I am trying to add the following:

dn: domainName=testme.net,ou=isp,dc=domain,dc=net
objectClass: top
objectClass: ispDomain
domainName: testme.net
mailboxLimit: 10
mailQuota: 100MB
accountStatus: enabled

I am adding with the following command:
ldapadd -x -v -w mypassword -D "cn=Manager,ou=isp,dc=domain,dc=net" -f
/root/second.ldif

And I get the following error:

ldap_initialize( <DEFAULT> )
add objectClass:
        top
        ispDomain
add domainName:
        testme.net
add mailboxLimit:
        10
add mailQuota:
        100MB
add accountStatus:
        enabled
adding new entry "domainName=testme.net,ou=isp,dc=domain,dc=net"
ldapadd: update failed: domainName=testme.net,ou=isp,dc=domain,dc=net
ldap_add: Invalid DN syntax (34)
        additional info: invalid DN

Any clues as th why I am getting this error, and how I go about fixing it.
Thanks in advance.
