If you want to add more attributes to the imported contacts than the example in this article provides,
install the Active Directory Schema snap-in. You can use the Active Directory Schema snap-in to view the
Object Class of a contact. This is helpful for finding the exact names of object attributes you want to add.
For example, to include the "home phone number" attribute, add a file header field that is named homePhone,
and then enter the phone numbers in the data fields beneath the homePhone header.
The Active Directory Schema snap-in provides the attribute names, descriptions, and provides a reference for
whether or not the attributes are mandatory or optional. To install the Active Directory Schema snap-in, add
the additional Windows 2000 Administrative tools by running Adminpak.msi from the %systemroot%\System32 folder.
Once the additional administrative tools are installed, the Active Directory Schema snap-in can be added to the
Microsoft Management Console (MMC).
Once a file has been constructed that conforms to the necessary structure, use Csvde.exe in Import mode to import
the information into the Active Directory. To import a CSV file, type csvde -i -f <path>\<filename> at a command
prompt, and then press ENTER, where the -i switch changes the Csvde.exe utility to Import mode, and the -f switch
requires the full path to the file name that is being imported. To see a list of available options for Csvde.exe,
type csvde /? at a command prompt, and then press ENTER.
