What's happening is that sshd is successfully authenticating via
public-key.

It then tries to check the account status via PAM which fails, because you
have Kerberos modules in your PAM config but public-key authentication
does not provide the Kerberos credentials required for the module to
perform those checks, and thus it fails.

If you don't use Kerberos then you can comment out the Kerberos account
(and probably session) modules.  (You might want to create a "sshd"
service in the PAM config specifically for it.)  If you do use Kerberos
then I'm not sure what your options are.

usually comes from bad judgement.
