# ssh2_auth_none

(no version information, might be only in CVS)

ssh2_auth_none -- Authenticate as "none"

## Description

array ssh2_auth_none ( resource session, string username )

Attempt "none" authentication which usually will (and should) fail. As part of this failure, servers will return a list of accepted authentication methods. If the server does accept "none" as an authentication method for username, this function will simply return `TRUE`.

Exemplo 1. Using ssh2_auth_none() to retreive a list of authentication methods.

`<?php $connection = ssh2_connect('shell.example.com', 22); $auth_methods = ssh2_auth_none($connection, 'user'); if (in_array('password', $auth_methods)) { echo "Server supports password based authentication\n"; } ?>`
