Thunderbird does this type of search as you type e.g. the name "Mike" into the To: field: "(|(cn=mike*)(mail=mike*)(sn=mike*))" attrs="cn mail" Which translates in english to: "find all entries in which cn or mail or sn start with "mike" and give me a list of the cn and mail attribute values from those entries". So, you can see that it really does not care which object classes you have used to compose entries that contain mail attributes. It is, however, hardcoded to look for the mail and cn attributes. For my accounts, I use at least the following classes: person organizationalPerson inetOrgPerson posixAccount I use uid for the naming attribute, but still include cn in the entry. -- mike
