[Dovecot] Authentication failed (migrate from 2.0.13 to 2.0.17)

[Dovecot user]

I tried to do the same 'dovecot -n' (dovecot 2.0.13, same config
file) :
# 2.0.13: /etc/dovecot/dovecot.conf
# OS: OpenBSD 5.0 i386
ffs
auth_mechanisms = plain login digest-md5 cram-md5 apop
base_dir =
/var/dovecot/
default_internal_user = _dovecot
default_login_user =
_dovenull
first_valid_uid = 1000
mail_location =
maildir:/var/mailserv/mail/%d/%n 

With dovecot 2.0.17 :

# 2.0.17
(684381041dc4+): /etc/dovecot/dovecot.conf
# OS: OpenBSD 5.1 i386
ffs
auth_mechanisms = plain login digest-md5 cram-md5 apop
base_dir =
/var/dovecot/
first_valid_uid = 1000
mail_location =
maildir:/var/mailserv/mail/%d/%n

Is it normal that there are no lines :
"default_internal_user = _dovecot" & "default_login_user = _dovenull"
??

I will try "auth_debug_passwords=yes", keep you informed.

Again,
thank you very much.

dovecot 2.0.13, all works. Perhaps in 2.0.17, something is missing in my
config file, or there's new keyword... ??

identical between those version. The CRAM-MD5 code is also identical
between those versions. I guess there could be some other seemingly
unrelated change that might have broken it for some reason.
