Windows 2008 IIS 7.5 installation problem

Thanks, I have placed the ini file in the root of the php folder.

The install seems to be working when I run the test script:
$cb = new Couchbase(“127.0.0.1:8091”, “”, “”, “default”);
$cb->set(“a”, 101);
var_dump($cb->get(“a”));

Whenever I run it without the username/password it works fine, when I do add the username/password the test script does not work though!? Is this username/password seperate from the initial couchbase server login, does each bucket have its own username/password?
