1. The lookup is NOT case-sensitive, Postfix maps the input key
to lower-case, and even if it had not, LDAP matches for "mail"
are case-insensitive.
2. Your problem is that the *output* of the query is not folded
to lower-case. This is not "case-sensitivity". What's case
sensitive in this case is the filesystem in which the maildirs
are stored.
3. The best solution is to ensure that all the "sAMAccountName"
values in Active Directory are in lower-case.
4. If you're using Postfix 3.0 or later, you could use "pipemap"
to case-fold the output of LDAP lookups, given some table
that downcases arbitrary input strings. No such table is
built-in. That would require new code. The table could be
loaded dynamically, but I don't expect you'll want to take this
route.
