SSH permission denied. #3
Description
https://phoenixnap.com/kb/ssh-permission-denied-publickey
Problem could be wrong configuration of the SSH server, but more probable is problem with the .ssh/authorized_keys file.
However within charon nodes the authentization is somehow done through the Kerberos. So no authorized_keys file should be necessary.
Try simulating this by removing Kerberos tickets https://web.mit.edu/kerberos/krb5-devel/doc/user/user_commands/kdestroy.html
