I have added a property called "division" to the User Profile
Properties.

To do this I followed this path:

Shared Services Administration: Intranet SSP > User Profile and
Properties > View Profile Properties > User Profile Property

I with to map this attribute to AD but the fields in the Property Import
Mapping area at the bottom of the page where this is done is not
available.

I have the only the Source Data Connection field showing the Source Data
Connection showing the Master Connection. I'm sure that this is a simple
switch that I have not enabled.
