Alias Domain Authentication

With the Domain Mapping System plugin, you can now let users login to alias domains and navigate protected pages.

In order to allow website visitors to login to user accounts on mapped subdomains of your website, you can simply enable the checkbox for Alias Domain Authentication:

Alias Domain Authentication Checkbox

This will allow users to login to Alias Domains of your website and remain only logged in to that Alias Domain. They are only able to access protected login pages that are mapped to the specified alias.

Selective Alias Domain Authentication

The dropdown checkbox allows you to selectively activate Alias Domain Authentication only on specific alias domains:

Activating Subdomain Authentication on Specific Subdomains

Multisite Requirements

If you are trying to configure Alias Domain Authentication on multisite, you must update the sunrise.php file mentioned in our multisite integration docs to change this string from this:

if ( ! is_multisite() || $is_admin ) {
    return $site;
}

To this:

if ( ! is_multisite() || ! $is_admin ) {
    return $site;
}
