Basically what I am trying to do is not the way it should be done, but for the moment I am just exploring possibilities.
We have started to experiment with Sharepoint Services (SPS). SPS can hook into Active Directory (AD) and pull out a list of users, along with contact details etc. The problem is it presents it in a silly format, with no real search capabilities. SPS also has the ability to create a linked Access table from the user/contacts list. What I wanted to do was query this table, but so far it doesn't work, and I don't really expect it to, because it links straight into AD.
I guess I need to do it properly, and start mucking around with LDAP to query AD directly, but this is a pain cos I don't have any experience with it.
There are a few tutes out there, but any further help is most welcome
