Active Directory Integration with Sharepoint

I have a SharePoint site with my company's active directory integration. When new personnel start to work, he/she is defined in AD. Then the record comes to SharePoint automatically.

If personnel information needs to be changed, it can changed in AD. But this change doesn't propagate to SharePoint site. Namely, if the name or surname needs to be changed, in AD it is corrected, but not reflected in SharePoint.

How can I change personnel information in SharePoint Designer/Central Administration?
