I”ve successfully used the following mappings with address book:

givenName (firstname)
sn (lastname)
title (job title)
o (company/college name)
telephoneNumber
mobile
facsimileTelephoneNumber
mail
street
l (city)
st (state)
postalCode (zip)
‘c’ (country)

Here’s some standard RFC mappings that I’ve tried that don’t work or aren’t used:

cn (full name)
ou (department?)
description
physicalDeliveryOfficeName
houseIdentifier
homePhone
organizationalStatus
displayName
employeeType

Apple’s Open Directory documentation, Appendix A, says the following should work, but they don’t:

postalAddress
pager
departmentNumber
buildingName

I’ve had no luck in finding something that will display department, mailstop, or physical building and room number location in Address Book.
