> Wagon calls scp/ssh always with a private key, even if none is specified unding the default .ssh/id_dsa. This prevents the interaction of ssh/scp with a running ssh-agent, that already manages the necessary private keys.
> Use case: I access several servers with different private keys with same or different user. Keys are added to a running ssh-agent as appropriate. Without explicit definition of the public key, external wagon fails now if I access such a server that uses not the standard key.
> Note: Same applies using putty and running the putty agent.
