This method causes its connection to be authenticated. If authentication is
|
|
enabled for the database server (it's not, by default), you need to log in
|
|
before the database will allow you to do anything.

This method is identical to running:
|
|
<programlisting role="php">

<![CDATA[
|

<?php
|
|
|
|
$salted = "${username}:mongo:${password}";
|

$hash = md5($salted);
|
|
|
|
$nonce = $db->command(array("getnonce" => 1));
|
|
|
|
$saltedHash = md5($nonce["nonce"]."${username}${hash}");
|
|
|
|
$result = $db->command(array("authenticate" => 1,
|
|
"user" => $username,
|
|
"nonce" => $nonce["nonce"],
|
|
"key" => $saltedHash);

?>

Once a connection has been authenticated, it can only be un-authenticated by
|
|
using the "logout" database command:

|
<programlisting role="php">
