hydra target ssh does not support password authentication

Question

I am using Hydra v8.1 downloaded and compiled from a tar file. I've managed to solve the standard problem of libssh support and now when I try to make an attack(I think it's called dictionary attack) on an SSH server, after specifying the following command:

hydra -l {username} -s {port} -P /Users/{UserName}/Desktop/{file}.txt {ip} ssh

I get the following output:

Hydra v8.1 (c) 2014 by van Hauser/THC - Please do not use in military or secret service organizations, or for illegal purposes.

Hydra (http://www.thc.org/thc-hydra) starting at 2015-09-30 10:59:49
[WARNING] Many SSH configurations limit the number of parallel tasks, it is recommended to reduce the tasks: use -t 4
[DATA] max 7 tasks per 1 server, overall 64 tasks, 7 login tries (l:1/p:7), ~0 tries per task
[DATA] attacking service ssh on port {port}
[ERROR] target ssh://{ip}:{port}/ does not support password authentication

I have enabled support for the required libraries and I am running an OS X environment.

Can someone indicate a solution to this problem? Thank you.

Note: If I manually log in with the username and password, the authentication grants access to the server.

SSH supports several different authentication mechanisms. The password authentication mechanism has the client send the password to the server as a password. The more-common keyboard-interactive authentication mechanism opens a channel between the client and an authentication process on the server. The client allows the user to directly interact with the authentication process, which is usually just a password prompt. This allows more complex features like multiple-factor authentication and pre-authentication warnings and checks.

So your target probably supports keyboard-interactive and not password authentication.
