Cryptage updated GUACAMOLE-1707:
--------------------------------
    Description: 
Hi guys,

I hope this issue doesn't exist (couldn't find similar).
I have a problem with Guacamole 1.4.0 and SSH.

On some Linux hosts I'm using SSH with 2FA (password + Google Authenticator or 
most frequently publickey + Google Authenticator).

Guacamole asks for password or passphrase when we connect to SSH then fails 
with "Log in failed. Please reconnect and try again".

It never asks for verification code.

In log files :
{code:java}
Public key authentication failed: Invalid signature for supplied public key, or 
bad username/public key combination

ERROR:        Public key authentication failed: Invalid signature for supplied 
public key, or bad username/public key combination {code}
I've checked in documentation, mailing list and Jira but couldn't find an 
answer.

Is there a way to get 2FA working with SSH connections ?

Thanks for your help and congrats for this amazing tool.
