# ssh2_auth_none

(PECL)

ssh2_auth_none -- Authenticate as "none"

## Description

mixed ssh2_auth_none ( resource session, string username )

Attempt "none" authentication which usually will (and should) fail. As part of the failure, this function will return an array 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"; } ?>`
