SharePoint Tip of the day – Unable to add users from your active directory ?

If you’re stuck with local accounts when you want to add new users to your SharePoint site, just make sure that the application account that you used for the specific web application has read access on the AD.
In a single server environment I was using a dedicated local account for the application pools, switching to a domain account solved the issue since the application pool account is the one that is use to query the Active Directory.

A small tip, but a huge relief !
