As far as I know, you don't need to import any LDAP schema into
Netscape Directory Server 4.12 (I assume this is what you
are using) to store the administered objects.
Are you seeing "schema violation" errors when you use jmqobjmgr ?
If that is the case, what lookup name are you using ? Does
your lookup name have the form:
"cn=myLookupName"
In most cases (it can be overriden), LDAP servers require lookup names
to have the above format.
