Longhorn: Active Directory Users and Computers console saves trips to ADSIEdit

One of the nice features I noticed about the Active Directory Users & Computers (ADUC) console in Longhorn server - in an object's properties, there's an Attribute Editor tab built-in, that allows one to directly edit an object's attributes. In previous versions, one had to use a tool like ADSIEdit to edit attributes not exposed by the ADUC user interface. The Attribute Editor will save trips to ADSIEdit for editing such unexposed attributes (for instance, the employeeID and employeeNumber attributes, as shown in the screenshot below). When directly editing AD attributes, it's important to ensure the validity of data so entered/changed, just like you would with tools like ADSIEdit.
