[IBMiOSS] PHP PDO dsn help

I am trying to test a PHP implementation of SimpleSAMLPHP where I use an
authorization that needs to sql a database on the IBMi. It looks like I
have most of it set up properly, but my PDO connection fails. This is
running in an Apache server running on that same IBMi.

Here are the relevant sections of code where it fails:


'dsn' => 'odbc:DRIVER={IBM i Access ODBC Driver};',
'username' => '',
'password' => '',
'options' =>
'HOSTNAME=127.0.0.1;PROTOCOL=TCPIP;CCSID=1208;UID=user;PWD=password',

try {
$db = new \PDO($this->dsn . $this->options, $this->username,
$this->password);
} catch (\PDOException $e) {
throw new \Exception('PDPModule:'.$this->authId.': - Failed to connect to
\''.
$this->dsn.'\': '.$e->getMessage());
}


This is the message that I get back when I try to test it:


SimpleSAML\Error\Error: UNHANDLEDEXCEPTION
Backtrace:

I have installed the unixODBC and unixODBC-devel packages using the Open
Source Package Management tool in ACS. I also downloaded and installed the
latest IBMiAccess_v1r1_PASE_AP rpm using YUM.

It appears that I am missing something to tell PHP where the driver is. I
have an odbcinst.ini file (in /QOpenSys/etc) that looks like this:

[IBM i Access ODBC Driver]
Description=IBM i Access ODBC Driver
Driver=/QOpenSys/pkgs/lib/libcwbodbc.so
Threading=0
DontDLClose=1
UsageCount=2

Can anyone point me in the direction of what to set to have it find the
driver?
