Authentication
If MongoDB is started with the --auth or --keyFile options, you must authenticate before you can do any operations with the driver. You may authenticate a connection by specifying the username and password in either the connection URI or the "username" and "password" options for MongoClient::__construct().
Example #1 Authenticating against the "admin" database
<?php
// Specifying the username and password in the connection URI (preferred)
$m = new MongoClient("mongodb://${username}:${password}@localhost");
// Specifying the username and password via the options array (alternative)
$m = new MongoClient("mongodb://localhost", array("username" => $username, "password" => $password));
?>
By default, the driver will authenticate against the admin database. You may authenticate against a different database by specifying it in either the connection URI or the "db" option for MongoClient::__construct().
Example #2 Authenticating against normal databases
<?php
// Specifying the authentication database in the connection URI (preferred)
$m = new MongoClient("mongodb://${username}:${password}@localhost/myDatabase");
// Specifying the authentication database via the options array (alternative)
$m = new MongoClient("mongodb://${username}:${password}@localhost", array("db" => "myDatabase"));
?>
If your connection is dropped, the driver will automatically attempt to reconnect and reauthenticate you.

How does this work for connections to replication sets?
Does the connection string become:
"mongodb://user:password@server1:27017,server2:27017,server3:27017"
For connecting to a replica set with authentication it is possible to use a connection string like the following (substitute the port numbers, replica set name and DB with your own)
$m = new MongoClient("mongodb://${username}:${password}@localhost:27037,mongodb://${username}:${password}@localhost:27038",
array("replicaSet" => "test"_replica, "db" => "mytestdb"));
The second member string "mongodb://${username}:${password}@localhost:27038" does not need the username and password - however, if the connection to the first member fails I have not tested to see if the username and password persist to the second member.
