Without it being apparent, pam_faillock was present on the OS. I had a user account that was 'locked' which I unlocked with the following:

faillock --user usernameGoesHere --reset

There are several places to check.

  • /etc/passwd - maybe the user has not access to a "valid shell"; if the line corresponding to this user ends with /bin/false, then this user does not have access to the command-line shell

  • /etc/hosts.allow and /etc/hosts.deny - access control

  • /etc/ssh/sshd_config - ssh configuration

  • /etc/security/access.conf - security setting

  • /etc/pam.d/sshd and /etc/pam.d/system-auth-ac - PAM settings

Using ssh -vv for verbose output may help.

And a user reported that reinstalling ssh resolved his issue.

Based on the answer from Chris, I used this command on a similar issue, with success:

faillog --user usernameGoesHere --reset
