SSH won't accept logins without password



Hello everybody,

could somebody please give me some clue, why I can't login into a
passwordless account.

This is what my /etc/ssh/sshd_config file looks like:
# This is ssh server systemwide configuration file.
#
# Modified:
#	- 16.01.2001: PermitEmptyPassword yes, PermitRootLogin yes
#	- 05.02.2001: Completely rewritten

# Connection Stuff
Port 22
ListenAddress 0.0.0.0


# Security stuff
# AllowUsers root viktor
HostKey /etc/ssh/ssh_host_key
IgnoreRhosts yes
IgnoreUserKnownHosts no
# KerberosAuthentication no
# KerberosOrLocalPasswd no
# KerberosTgtPassing no
# KerberosTicketCleanup no
KeyRegenerationInterval 3600
LoginGraceTime 600
PasswordAuthentication yes
PermitEmptyPasswords yes
PermitRootLogin yes
RhostsAuthentication no
RhostsRSAAuthentication no
RSAAuthentication yes
ServerKeyBits 768
StrictModes yes


# Misc stuff
# AFSTokenPassing no
CheckMail no
LogLevel INFO
PrintMotd no
# PrintLastLogin yes
SyslogFacility AUTH
UseLogin no
X11Forwarding yes


This is the output I get when trying to log into a passwordless user
account (viktor):
# /etc/init/ssh restart
# ssh -l viktor bart -v

viktor@bart's password:

Huh?!

I tried the config file of an old slink machine where this works great
to no avail.  Won't log me in!
Also note, that I have uncommented the Kerberos* and AFS* and
PrintLastLogin configuration options, because sshd would complain about
them.  They are listed in the man page though.  Am I missing some
spelling mistake or what is going on?  Oh yeah, this is on a fairly
recent woody system (last dist-upgrade was two weeks ago).

TIA,
Viktor
