The "normalize" patch included by Debian isn't that far off from
what the option "usercase_tolower" already offers:
username_tolower (on|off)
Convert usernames to all lowercase before login/authentication. This
is useful with authentication backends which ignore case during
username lookups (such as LDAP).
Here's what the Debian patch
(0013-Normalize-the-authentication-ID.patch) says:
By normalize, it is intended that;
1) Authentication IDs all can be lowercased for more accurate
comparison without being volatile to, say, user error, and
2) Any leading or trailing blank space can be stripped
And then they go on to patch, mostly, lib/auth_unix.c (as well as
global.c, imapoptions, etc.).
Other than trimming white space, I can't see what the big deal is
with this patch.

Oops. Should I open an issue for a feature request? I'm
surprised that's
not something many sites want ...
OK, I've never heard of this thing. What is it?

Right, so it's something to normalise the userid when you log
in.
It will definitely have to be rewritten for Cyrus 3+, because
all that
stuff got moved into mbname_t and friends.
Perhaps my assumption that the option is necessary is wrong? But I
know for certain that our webmail users use varied case-spellings
of their user names, because in earlier versions of our webmail
system they would get different user profiles depending on how
they had entered their user names ;-)
Bron, how does Fastmail deal with that? Do you simply force users
to use the canonic spelling? I guess we could do that, but I'd
rather not.
Cheers
