Correct, should be a simple case of: <running as intended user> ssh-keygen -b 2048 cat ~/.ssh/id_rsa.pb >> ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys
For a shared home directory setup. It's the reason why we haven't bothered getting in the business of user key management because *usually* it's that straightforward...

Management node is running PCM 4.1.1.1 with xCAT 2.8.2 underneath. Since it's a comparably small cluster and only few users, they are administered locally via /etc/passwd on the MN. /home is exported via NFS and mounted on the CNs. It is possible for a user to log in via ssh on the MN. However, the same user cannot connect to any CN, neither with password nor without. What has to be done to make login on the CNs possible for common users? And if this works, I assume passwordless login should be possible if the public key is included in ~/.ssh/authorized_keys with permission 600, is that correct?
