As a network administrator I am frequently required to create scripts to retrieve particular  information about users from Active Directory.  Here are some useful AD attributes for you to use in your scripts.

• DisplayName
• cn – Common Name
• mail = email address
• c = Country
• homephone = no explanation needed here
• l =  City
• mobile
• postalCode = post code
• st = State
• streetAddress
• telephoneNumber = Office number
• whenCreated – the day the object was created

There certainly are more but for me these are the main ones for the reports I use.
