We have our SDP hooked up to AD and use it purely as a Helpdesk Management Tool. The Self service Portal is unused.

Everyting works fine more or less. We're a school and we only want our Teachers to be listed in the Requesters. Importing them is fine, we asset them assets and when they need help they email ICTSupport which is picked up by the Helpdesk and we can see all their details. The problem is the Students.

If a Student emails the Helpdesk, which is something we encourage them to do, SDP will create a new Requester account for the Student. This makes managing the assests a real pain as the list of Users gets longer and longer over time. It's also a problem with Spam Emails. Any that do slip through the net get a Requester account creted too!

Is there a way to turn this off and make it so that New Requesters are only added Manually or through Import?

I have the Dynamic User Addition set to "No" but new users keep appearing.

Any ideas?
