Problems with the REST API post a new user

Hi

I have automated creation a a couple of hundred users, using POST via the REST API.  The accounts were created, and look ok, but we cannot login to them as we do  not know the passwod.

Is there a default password?

here is some sample code, which creates the users without trouble.

// Tell curl to use HTTP POST

curl_setopt ($session, CURLOPT_POST, true);

$parts[0]="test.name";

$parts[1]="test full name";

$parts[2]="test@fugro.com.au";

$url = "http://build2.fugro/youtrack/rest/admin/user?";

curl_setopt($session, CURLOPT_URL, $url);

$xml = "login=" . $parts[0] . "&" . "fullName=" . $parts[1] . "&" . "email=" . $parts[2];

curl_setopt ($session, CURLOPT_POSTFIELDS, $xml);

$response = curl_exec($session);

echo $response."\n\n";
