I’ve tried both idmap_rfc2307 and idmap_nss backends; but if my LDAP uidNumber doesn’t match my AD uidNumber, mapping doesn’t appear to work. This surprises me because the _names_ match (AD sAMAccountName and LDAP uid (name)), and I thought that the whole point of idmap was to translate an AD username into a UNIX uidNumber. What am I misunderstanding or doing wrong?

It sounds like you are trying to map users & groups from two places at
once, if this is the case, I don't think it is ever going to work.
what do you use the ldap for ?
