Import and sync users from AD to pfSense

[Boyz]

Hello,

is there a way to import and sync the users from AD in to pfSense as local users?
We have one Active Directory Server (Win 2008 R2) outside the company, in case  the AD Server is down, the users still should be able to use Captive Portal Authentication.

Thanks,
Boyz

Writing a small PHP file that parses a CSV file, and imports it in local user manager.
The CSV is the exported user list from your AD.

Syncing password might be the only issue where one has to think.
