I have a SharePoint 2010 site.
It uses Active Directory to manage users.
We have multiple customers using this site on their own sub sites.
The users can not access each others sites.
But when I go to assign a task to someone in the issue tracker, I can search and see all the users in the active directory.
We only what to see the users with access to the site.
Is there a way to make this work and not share my entire Active Directory User list with everyone?
