Hi,
I've searched in the wiki and in the mailinglist archives but haven't
found anything about password character sets within the dovecot
authentication deamon.
My problem is that we have users with passwords containing scandinavian
characters (äöå, umlauts) and the debug log shows that different clients
send the password in different charsets. The passwords are stored in a
Mysql table, if that makes any difference.
Outlook Express with LATIN 1 (ISO-8859-1):
Nov 18 16:56:39 resilar dovecot: auth-worker(default):
sql(fgr-1,193.64.206.190): Password mismatch
Nov 18 16:56:39 resilar dovecot: auth-worker(default):
sql(fgr-1,193.64.206.190): MD5(<E4><E4>kk<F6>si<E4>) !=
'$1$xMPPHRdL$I0mrlPi5FMtwauSf20vjz0'
MacMail UTF8:
Nov 18 17:23:37 resilar dovecot: auth-worker(default):
sql(fgr-1,193.64.206.190): Password mismatch
Nov 18 17:23:37 resilar dovecot: auth-worker(default):
sql(fgr-1,193.64.206.190): MD5(ääkkösiä12) !=
'$1$xMPPHRdL$I0mrlPi5FMtwauSf20vjz0'
Is there a setting that "forces" the authentication daemon to convert
the provided password to a specific charset before the comparison takes
place, or how should one handle this?
