Can not authenticate to server

Greetings,

Getting login failure against an Araknis switch.
I can login to this device without an issue with Putty with the same credentials.

This same code works fine with other devices (Cisco, HP, etc.).

Code used:
```
final SSHClient sshClient = new SSHClient(new DefaultConfig());
sshClient.addHostKeyVerifier(new PromiscuousVerifier());

try {
sshClient.setConnectTimeout(timeout);
sshClient.connect(address, port);

sshClient.authPassword(user, pass);
} catch ...
```

Log:
```

Any idea what could be wrong or how to further debug this?

Thanks!
