What is LDAP?

Lightweight Directory Access Protocol (LDAP) is a set of protocols used for accessing online directory services. By using TCP/IP, LDAP allows clients on multiple platforms (i.e., Windows, Macintosh, Unix) to access centralized directory services.

Note: The UITS services in this document may not be available to users on the Fort Wayne campus. Many computing services at IPFW are administered locally, by IPFW Information Technology Services (ITS). For more information, see the ITS web site.

At Indiana University, UITS currently does not provide an official LDAP service. However, a Microsoft LDAP implementation is in service to support IU's Exchange email systems via the Outlook email client. Though UITS does not support LDAP service for other email clients, you may find some clients that are able to use it successfully.

The following are instructions for configuring clients that are known to work with IU's LDAP implementation:

• In Entourage for Mac OS X, how do I access the ADS Global Address List?
• In Outlook, how do I search through the ADS Global Address List if I'm using IMAP?
• In Outlook Express for Windows, how can I find someone's email address?
• In Mac OS X, how do I search for an address in the ADS Global Address List?
