LDAP Query Basics
This would return all objects that have the first name of John. Parentheses are included to emphasize the beginning and end of the LDAP statement.

To obtain the ADModify tool, contact Microsoft Product Support Services. For more information about how to contact Microsoft Product Support Services, see the Microsoft Help and Support Web site .

With large Active Directory environments, it is not always easy to add an entire organizational unit (OU) that could have thousands of users in it to the list on the right side, and then parse through all of them to find the users you need to change. There is an alternative. On the first screen, choose Modify Existing User Attributes and click Next. On the Modify Active Directory Users screen, there is an Advanced button.
If you click the Advanced button, the Custom LDAP Filter dialog box appears. In this dialog box, you type the LDAP filter that you want to use. In this example, you only want to list the groups that are mail-enabled. It would look like the following.
Next, click OK. Select the OU or the domain where you want ADModify to search. If you want it to look in lower-level containers within the one you selected, make sure to select Traverse Subcontainers when Enumerating Users. Click Add to List. and then click Yes when warned about how long it could take. The objects that meet the criteria you specified should now appear in the right pane.
From here, highlight the objects that you want to modify, and continue with the wizard.
