Using Remote Authentication

Remote authentication allows you to integrate your organization's authentication system with KBPublisher. Configuration requires only a few simple steps.

Before you start:

• We assume that you have some experience with remote authentication, with PHP, and with the system you are connecting to.

Steps to enable Remote Authentication

• Set the config variable $conf['remote_auth'] in the file admin/config.inc.php to 1


• Set required values for constants in file admin/lib/custom/remote_auth.php


• Customize the _remoteDoAuth function in the file admin/lib/custom/remote_auth.php to authenticate the username and password passed to it against your own authentication system

Quick summary of the process

• End User sends an authentication request by logging in to the knowledgebase
• Remote Authentication checks for valid user credentials
• KBPublisher authenticates the user .

Customizing the remoteDoAuth function

In your installation there is a folder admin/lib/custom. Within that folder is a file called remote_auth.php. This file contains the _remoteDoAuth function. Customize this function to do authentication against your internal system by using the username and password provided.

Here is a simple example of the function customized to authenticate against a MySQL database:

function remoteDoAuth($username, $password) {

    $user = false;
    $db = &DBUtil::connect($conf);

    $sql = "SELECT 1 FROM ss_user WHERE username = '%s' AND password = '%s'";
    $sql = sprintf($sql, $username, $password);
    $result = &$db->Execute($sql) or die(db_error($sql, false, $db));

    // if found
    if($result->RecordCount() == 1) {
        $user = 1; // assign a user id, this user id should exists in kb user table
    }

    return $user;
}
