Comment 3 for bug 1690485

Hi Kevin,
I quickly checked in the default config in zesty but ssh logins are working fine (pw logins is what I tested).

There must be more to your config that triggers this.
Is what you see in dmesg an apparmor denial or something else?
Could you attach your dmesg covering the issue that you see?

You logs attached so far only hold plenty of:
May 12 19:17:15 hostname sshd[4241]: pam_unix(sshd:auth): check pass; user unknown
[...]
May 12 20:51:55 hostname sshd[8608]: error: maximum authentication attempts exceeded for root from 192.168.1.1 port 9990 ssh2 [preauth]
May 12 20:51:55 hostname sshd[8608]: PAM service(sshd) ignoring max retries; 6 > 3

But those could just as well be from your testing.

I imported your sshd config as auto attached to the report, restarted it and it still worked fine. So we really would need more to help debugging.
