User accounts are security principals, which means permissions and rights can be assigned
to them so that users can access network resources and perform certain operations on their com-
puters. You can create two other user-related accounts: contacts and distribution lists, explained
in the following section.

Using Contacts and Distribution Lists
A contact is an Active Directory object that usually represents a person for informational
purposes only, much like an address book entry. Like a user account, a contact is created in
Active Directory Users and Computers, but a contact isn't a security principal and, therefore,
can't be assigned permissions or rights. The most common use of a contact is for integration
into Microsoft Exchange's address book. The Full name field is the only information
required to create a contact, but a contact's Properties dialog box has General, Address,
Telephones, Organization, and Member Of tabs (see Figure 5-11) for adding detailed infor-
mation about the contact. You use the Member Of tab to add a contact to a group or a dis-
tribution list.
