Auto Append Domain

Purpose

To allow people to log in with simple first.last names without having to add domain information.

In this case I was using a plugin for kerberos based authentication. If that failed, I needed users to log in with their standard user names. To do this I needed Wordpress to add the domain to the user name and use it as their "email address".

• In wp-login.php, add the following lines before
  

/**
* Output the login page header.

if (isset($_POST['log'])) {
$testinput = $_POST['log'];
if (!preg_match('/@/', $testinput)) {
$_POST['log'] .= '@domain.tld';
}
}
