JLAB Email Directory Services

The Computer Center provides JLab an email directory service that is available for use by conforming email clients, which include Mozilla Thunderbird and Microsoft Outlook.

The service provides automatic look-up of names, phone numbers, and email addresses of Jefferson Lab personnel. Your mail program must be able to use the standard "light-weight directory access protocol" (LDAP).

Two pieces of information are needed by clients of the service: the host name of the server and the "search root" of the database. In our case, these are, respectively:

• ldap.jlab.org
• o=Jefferson Lab, c=US

Once this information is correctly entered in a mail client's configuration, lookups of email addresses will be automatic for mail addressed to on-site people.

To add directory services to Mozilla (Thunderbird) email clients, do the following:

1. Open your email client and log in with your JLab password
2. From the Tools menu, open "Account Settings..."
3. Select "Composition & Addressing" on the left
4. Select the radio button for Use a different LDAP server: and hit the 'Edit Directories' button
5. Hit the 'Add' button and enter the following information:

• Enter "JLab Directory Server" in the Name: field
• Enter "ldap.jlab.org" as the LDAP server in the Hostname: field
• Enter "o=Jefferson Lab, c=US" in the Base DN: field
• Enter "389" in the Port Number: field
• DO NOT check the "Use secure connection (SSL)" box!

Hit 'OK' to accept the values
6. Hit 'OK' again to accept and exit the preceding box
7. Then, select the "JLab Direcotry Server" from the drop down menu
8. Hit 'OK' again to exit Account Settings.
9. Finally, exit your email client and log back in to ensure the changes take effect

To add the directory services for Outlook do the following:

1. From Outlook's main page, follow this path: Tools -> Accounts -> Directory Service -> Add -> Directory Service
2. Enter "ldap.jlab.org" (leave the "log on" option UNSELECTED).
3. Select "yes" for "check address."
4. Enter "JLab Directory Server" for "friendly name."
5. Finish
6. In the Directory Service window, select "Advanced."
7. Leave "port" as 389.
8. Enter "o=Jefferson Lab, c=US" for "search base."
9. Click OK then Close.

Your email composer and address book will now be able to get information directly from our directory service server. For other LDAP-compatible clients, the procedure should be similar.

The actual use of this feature varies a bit from one mail program to the next. With Netscape, for instance, the program attempts to complete the address information as you type or when you move to the next field using a TAB. With Outlook, the actual directory check does not occur until you send the mail; then a list of possibly correct addresses is presented from which you can choose.

The data provided by the directory server are updated daily from CIS. If you note a mistake, or if you have trouble with the setup, please call the Helpdesk (x7155) between 1PM and 4PM on workdays.

Eventually this service will be integrated into an international directory of High Energy and Nuclear Physics labs.
