Summary: is there a way to have windbind fold a mixed case username into lowercase? If the NT DOM account is "Brian", I want to be able to instruct winbind to actually tell pam that the account is "brian".
Situation: I have an NT PDC with which users were added by their first name, first letter capitalized. For example, my account would be "Brian". As we all know however, NT usernames are case insensitive, so I can log in with "Brian" or "brian" -- they are equivillent. When I give out an Exchange e-mail address I can give "[EMAIL PROTECTED]" and "[EMAIL PROTECTED]" and they both mean me. Now I am putting in a postfix/cyrus mail server and want to be able to use winbind to authenticate the imap accounts to the NT PDC and deliver mail. The problem arises that Linux/Unix are not case insensitive and Brian and brian are two different users and two different mailboxes. But as a statement of policy I am able to dictate that usernames shall always be all lower case. And because of the case insensitiveness of NT, I can be safe in doing so and not causing problems for grandfathered accounts. However, I need to deal with the existing accounts/people which are of the format "Firstname". I can force cyrus to convert the account name to lowercase before delivering to a mailbox so that when somebody mails to "[EMAIL PROTECTED]" it goes into the "brian" mailbox. But when they log in to Cyrus via PAM/winbind, they need to have the case matching exactly (i.e. Brian, not brian) for the authentication to succeed (contrary to NT), and even then, cyrus gives them the uppercase-first-letter mailbox, not the lowercase mailbox (I can only force cyrus to _deliver_ to the lowercase mailbox, not force the mailbox name to lowercase for log in purposes). What would be ideal would be that I could tell winbind to force account names into lowercase before returning them to the NSS (i.e. as a passwd entry), but I see no options to do this.
