Q: When I use MIT's LDAP in Thunderbird, why can't I see the office address?

Answer

Default settings for Thunderbird do not include an address book mapping that matches the field in LDAP for office address [LDAP: roomNumber.]
To see this field you must manually add the mapping to your "pref.js" file.

To manually add the office address field:

1. Go to the preferences file "pref.js." This is usually found in
   
   C:\Documents & Settings\<username>\Application Data\Thunderbird\Profiles\<random string>.default
   
   
2. Find the following section:
   
   user_pref("ldap_2.servers.MIT.auth.savePassword", true);
   user_pref("ldap_2.servers.MIT.description", "MIT");
   user_pref("ldap_2.servers.MIT.filename", "abook-1.mab");
   user_pref("ldap_2.servers.MIT.maxHits", 100);
   user_pref("ldap_2.servers.MIT.replication.lastChangeNumber", 0);
   user_pref("ldap_2.servers.MIT.uri",
   "ldap://ldap.mit.edu:389/dc=mit,dc=edu??sub?(objectclass=*)");
3. At the end of the above section, add the following:
   
   user_pref("ldap_2.servers.MIT.attrmap.WorkAddress2", "roomNumber");
   
   Note: "ldap_2.servers.MIT" may have a different number and/or name depending on how you configured your LDAP setup.
   
4. Save the file.
5. Restart Thunderbird.
