windfall is on a distinguished road

Hi,

I hope anybody can help. After hours of reading forums and many tries, I don't know what else I can do.
I have OS X 10.4.11 and it is not possible to login via ssh, neither from an other machine nor from localhost regardless of username.
"Permission denied, please try again."
In secure.log:
"Jan 3 11:36:45 mac-g5 sshd[444]: Failed password for testuser from ::1 port 49287 ssh2"
The password was correct because it was trivial.
ssh -vvv didn't show any suspicious fact.

The very strange thing about this is a few days ago, it was possible to login and sometimes not. Meanwhile login fails everytime.
If I configure PubkeyAuthentication, it is possible to login.
I had copied the sshd_config from another Mac with OS X 10.4.11 on which ssh works fine - no success.
I suspect that something is wrong with pam, but I have no idea what.

thanking you in anticipation
Code:
