The mechanism is this: o broker deploys a public key in ~/.x2go/authorized_keys on X2Go Server o X2Go Client receives the corresponding private key o (the above is already flawed, no private keys should be sent over networks, I will file another bug for that) o in SSHd, the ~/.x2go/authorized_keys must be configured as potential place for authorized_keys file If the last step is forgotten, SSH authentication with X2Go Client=20=20 against=20the X2Go Server fails. If that fails, my expectation would be a fall-back to username /=20=20 password=20authentication. But what happens, is: X2Go Client "gets stuck" in the session startup=20=20 procedure=20(it's not a real freeze), it does not return to the login=20=20 dialog=20widget anymore. Options remaining: closing X2Go Client and=20=20 reopening. I=20stumbled over this because of a configuration in SSH daemon on one=20= =20 of=20my test boxes.
