SharePoint AD Information Sync provides a short-cut to set Active Directory sync to a SharePoint List based on profile synchronization.
You can customize the Active Directory sync by setting Sync Profiles. The users/computers which you want to sync can be specified by Organizational Unit (OU), LDAP query String, and specific accounts can be excluded in the AD sync setting. Besides, AD sync can be performed manually or automatically if you set a schedule on it.
One AD-sync profile can set one-way sync from AD to one SharePoint list. With more sync profiles, you can gather information from multiple AD to one SharePoint List or from one AD to multiple SharePoint lists.
To create a SharePoint AD sync profile, first select the object SharePoint List and input AD login info. Second, specify Active Directory sync scope by modifying LDAP query string or selecting Organizational Unit from the OU structure. Third, Set column mapping for the synchronization. Save this profile and you can begin this AD-sync to SharePoint manually. Or you can set a schedule to operate this AD sync automatically. In this case you need to active the AD Information Sync Timer Job Feature in your web application in Manage Web Application Features.
