[Web-cyradm] RE: Auth Failed in account with upper case character

[John Tobias]

HI Bjoern,

Thanks for the tip. I added and set to no the lmtp_downcase_rcpt and 
username_tolower. Then I restarted the cyrus, postfix and saslauthd.

I tried to login #cyradm --user 4356Z localhost, the behavior and the error 
was still the same.
saslauthd[3083]: do_auth : auth failure: [user=4356z] [service=imap] 
[realm=] [mech=pam] [reason=PAM auth error]

Anymore idea?

Thanks,

John
