Yes as Rowland said only a minimum of attributes are transferred.
We wrote a script for that. I'll add it at the end of the mail. Maybe it
will help you.

Here is the script (A colleague wrote this. I just clean it up for
posting). It queries the old LDAP Server for the required data, puts
together an ldif and writes that to the AD. As we were new when we wrote
this forgive us for any things done wrong or to complex :-)
