Subject: case sensitivity/insensitivity with postfix, cyrus, and ldap
From: Andrew Diederich (andrewNETdelivery.com)
Date: Thu Apr 27 2000 - 15:29:43 CDT

Things were going along swimmingly until I tried using an uppercase mailbox
name. At some point in the mail delivery the mailbox get changed from the
correct uppercase name to an incorrect lowercase name.

An odd thing is if I telnet right to port 143 and login to the imap server,
I can login with both uppercase and lowercase mailbox names. Below are some
maillog pieces, an ldap entry, the cyrus bit from master.cf, and heck, why
not a postconf -n. What flags can I add where for more helpful debugging
info?

So, from all this can someone point me to where the case is being chagned,
and (hopefully) how to stop it?

ldap:
uid=AUID123lowercase, dc=NETdelivery
uid=AUID123lowercase
userpassword=password
maildrop=AUID123lowercase
mailacceptinggeneralid=mixed
objectclass=account
