Actually the whole suggestion is pretty well useless unless you first
re-implement some or all of getpw*() functions since there's no way to
tell them what string comparison function to use. ;-)
In fact it gets even trickier if other user databases are in use, such
as YP/NIS/NIS+. In the end you have to scan the whole thing anyway, and
that can quickly go from expensive to *very* costly if it's not done
carefully.
If you do have a large user-base and/or use YP/NIS, etc. then there's
likely only one thing you can do if you want case-independent mailboxes,
and that's to force all your users to have lowercase-only user-names.
Then in the user director you can simply map all mailbox names to
lowercase and then pass them to the local delivery agent if they match a
local user.
Of course you could always use the old trick of building a separate
database that includes all case variants to map to the true case of the
user-name....
