When trying to ssh to a public interface on my Supermicro Linux Ubuntu (22.04.5 LTS), I am only denied using the correct password repeatedly.
Troubleshooting I have already tried:
• Created multiple new users with simple passwords.
• Generated a key pair (PuTTYgen) and correctly installed the public key in the user's authorized_keys file.
• Identified and uninstalled the aadsshlogin package (Azure Active Directory/Arc component).
• Manually attempted to reinstall libpam-runtime and openssh-server to restore default PAM files.
• Manually edited /etc/pam.d/sshd to bypass the broken @include common-auth file and directly inject the working command: auth required pam_unix.so use_first_pass.
• Changed interfaces, changed static IP assignments, restarted interfaces, etc.
Please provide suggestions, documentation, if you've seen this before.
