ssh login fails with active certificats, because they do not match and there is no password request.

I've got an AIX server, where I'd like to login as a different user, but
the SSH-Certificates I've loaded, do not match.

The login fails without requesting the password for the account:

[ewer@solewer:~]$ssh gvs@aix
Received disconnect from XXX.XXX.XXX.XXX: 2: Too many authentication failures for gvs

After changing the MaxAuthTries in /etc/ssh/sshd_config on the AIX and restarted
the SSH-Service with

stopsrc -g ssh
startsrc -g ssh

I can now login into the AIX server because the SSH-Shell asks for the password.
