The problem you will face is that many, many, many AD Attributes and
ObjectClasses are not declared in ApacheDS. You first have to create all
those schema elements in ApacheDS in order to be able to load the
entries in ApacheDS.

I must warn you here : we are talking about hundreds of missing schema
elements, and worse of it : Microsoft has done a *great* job fucking up
the compatibility of LDAP by changing many little and not obvious things
in their LDAP implementation, making it very tedious to load their
schema in a compliant LDAP server.

Bottom line : yes, it would be cool to be able to do that, no, it's not

OTOH, do you really need to load all the entries from a AD server into
another LDAP server ? What is your use case ?
