SUMMARY
Microsoft Outlook includes support for the Lightweight Directory Access Protocol (LDAP). LDAP is a directory service implementation that allows access to user information using the X.500 directory. If you use this protocol, searching is much faster than if you use the Directory Access Protocol (DAP).

How to Add an LDAP Directory Service to Outlook 2002
To set up an Internet directory service, your Internet service provider (ISP) must offer a directory service. Use the following steps to add an LDAP account:
 * 1) On the Tools menu, click E-mail Accounts, click Add a new directory or address book, and then click Next.
 * 2) Click Internet Directory Service (LDAP), and then click Next.
 * 3) Type the server name of the directory service that you want to configure. For example, the Bigfoot service directory server name is ldap.bigfoot.com.
 * 4) If the directory service you are adding requires a password, click This server requires me to log on, and then complete the necessary information.
 * 5) Click Next, and then click OK when you receive the prompt that tells you to restart Outlook.
 * 6) Click Finish.

How to Use LDAP to Find Someone on the Internet
LDAP searches are enabled through the Outlook Address Book. You can search by using the Contacts database in Outlook or choose from the Internet directory search services. These services include Bigfoot, InfoSpace, Switchboard, WhoWhere, and others. Each of these services have World Wide Web sites that you can reach in the Find People dialog when you click the Web Site dialog box. Use the following steps to use LDAP to find someone on the Internet:


 * 1) On the Tools menu, click Address Book.
 * 2) Under Show Names From the, click your LDAP server (for example, ldap.bigfoot.com).
 * 3) In the Look in box, click the directory service that you want to use for your search.
 * 4) On the People tab, type a name or e-mail address, and then click the Advanced tab to further define your search criteria.

NOTE: Outlook defaults the selected search form to the Contacts database from your address book. This form contains the following five fields: Name, E-mail, Address, Phone, and Other. The predefined directory services forms contain only the Name and E-mail fields.
 * 1) Click Find Now.

LDAP Search Configuration Tips
If you are experiencing a slow response from a directory server or the server does not respond, use the following settings to optimize the LDAP searches:
 * 1) On the Tools menu, click Accounts, and then click the Directory Services tab.
 * 2) Select an LDAP service to optimize, and then click Properties.
 * 3) Click the Advanced tab.
 * 4) Move the slider to the right to increase the time the address book takes to search the directory service. The default setting is 30 seconds.
 * 5) If a starting point or root is provided by the directory service provider, enter this information in the Search base field.
 * 6) Click Use simple search filter. A simplified search query may produce better search results.
 * 7) Reduce the Maximum number of matches to return.

NOTE: The default port for LDAP service is set at 389. If you are using Outlook in a local area network (LAN) environment, check with your network administrator to assure that proxy or firewall configurations do not interfere with this setting. Additional query words: OfficeKBHowTo Four11
