Admin class does not get passed credentials in DSN

[ollyollyollyltd]

The Admin class takes an (maybe) authorised client as it's first argument.

$client = new couchClient(http://username:[email protected]:5984),'myDb');
$admin = new couchAdmin($client);

When the admin class wants to make requests it uses the DSN from $client->dsn(), however the username and password is stripped from the DSN in the __construct of couch class:

// couch.php line 68
$this->dsn = preg_replace('@/+$@','',$dsn);

This means that the DSN used by the admin class will not allow the object to authenticate with the database.

At the moment I am extending the client class as so:

// MyClient.php
public function __construct($dsn, $dbname, $options = array() ) {
    parent::__construct($dsn, $dbname, $options);
    $this->dsn = $dsn;
}

This allows any admin classes to use the 'original' DSN, and thus authenticate.

Am I misunderstanding how this should be used or is this an error?
