Good morning Brian,
There is now a module available to connect to Active directory that can be used with CardExchange Ultimate, you would need to contact your supplier to obtain pricing on this.
Do you know who you purchased CardExchange through ?
If you can provide the serial number we can check for you if needed.
Regards,
Craig
