I have a license for the migration tool. I am trying to do a dry run to test things out for migrating mail accounts over from a cpanel server (so I can retain the users' passwords). I originally had the ispconfig host configured to only allow ssh access with a public key and root was disabled. The ISP migration script requires the root to login with a password unfortunately I can't seem to reverse my host set up of the sshd. I have changed the /etc/ssh/sshd_config file with the following: I can login with passwords with non-root user accounts, but still not with the root user. I have even re-initialized the sshd configuration files (dpkg-reconfigure openssh-server), restarted sshd and still the same result. The auth.log shows "error: PAM: Authentication failure for root from ..." On a clean, new server installation I can login as root/password via ssh. ISPConfig is running on the server so I don't want to start over again :-/ but for the life of me I don't know what I am missing. So actually two questions: 1. can I just copy the migration public/private keys to get beyond this step, and/or 2. does anyone know where else I should be looking to fix the plain-text password for ssh? Thanks!
