I found this thread and wasnt sure if my problem was related:
http://www.silverstripe.com/site-builders-forum/flat/637

My version of php is: 5.2.2

Might this be the reason my code isnt working?

Security::setDefaultAdmin("admin", "password");

<?php
global $project;
$project = 'mysite';

global $databaseConfig;
$databaseConfig = array(
"type" => "MySQLDatabase",
"server" => "pedstaff.fatcowmysql.com",
"username" => "peds",
"password" => "saf3ty",
"database" => "ss_mysite",
);

// Sites running on the following servers will be
// run in development mode. See
// http://doc.silverstripe.com/doku.php?id=devmode
// for a description of what dev mode does.
Director::set_dev_servers(array(
'localhost',
'127.0.0.1',
));
// This line set's the current theme. More themes can be
// downloaded from http://www.silverstripe.com/cms-themes-and-skin
SSViewer::set_theme('peds');

Security::setDefaultAdmin("admin", "password");

?>

There are times when the password and username are correct but you're not redirected to the admin page. Read the notification message in the form. If it says you are logged in as ... try to hit this url http://peds.org/_devsite/admin manually.

I see what your saying but it didnt like that.

Umm what did it say exactly?

It did nothing, just the login screen.

that's weird. well, make sure the username and password are correct and hit the url i mentioned eariler after the login process.

Not too sure what you mean by hit it manually.
