Thanks for the comment. There is something strange. It stands following in the documentation:

The example describes a remote SSH connection to the computer example. 
computer with the username root. Set the optional password password property 
to make SSH login with a password instead of the key file

In our context, we log in using a key file. I don't think password was meant to be passphrase. I think the driver just waits for an input request and enters the passphrase as the password.

But it works.

Hi @wdmegrv, AFAIK the password supplied to the NetworkService is the password used to login via SSH and not the passphrase used to decrypt the private key. @fanougon needs a key based login since password login is disabled.
