Authentication does not work

[mondynus]

HI, i try to do this
$cassandra->useKeyspace('keyspace','username','pass');

but i get InvalidRequestException. I found that there are not defined arrays keys ("username" and "password") of auth. request. After i fixed it, there is another exception in other part of library.
I use Cassandra 1.2.4

Please help me solve this problem. Thanks so much

I have solution. As i have written, there is mistake in "CassandraConnection" class in method useKeyspace. It is necessary to replace
$request = new cassandra_AuthenticationRequest(
array('credentials' => array($username,$password))
); to
$request = new cassandra_AuthenticationRequest(
array('credentials' => array("username"=>$username,"password"=>$password))
);
Second exception was caused by bad set permisions to keyspace.

Check it now, hope it works, no time to test myself. Open again if the issue persists :)
