Vouchers sync with Carp don't work

[eviltrooper]

Hello,

is set up 2 pfsense machines with Captive Portal.

everything works fine.

Sync from Master to slave works..

The only Problem i have now is the Vouchers Sync!

i enable the sync on the BACKUP System  but the IP from Master port and username and PWD.

following error Message appears ont the Backup System:

The following input errors were detected:

An error code was received while attempting CaptivePortalVoucherSync XMLRPC sync with https://192.168.128.250:443 - Code 2: Invalid return payload: enable debugging to examine incoming payload

on my Master in the Log file this:

php[2938]: /xmlrpc.php: Disallowing CARP sync loop.

i understand the Problem because if i use the BACKUP System for the Vouchers Master it will works.

Because the Master System disallowed to update anything on the Master.

i used version
2.0.1-RELEASE (amd64)
built on Mon Dec 12 18:16:13 EST 2011
FreeBSD 8.1-RELEASE-p6

is ther an Fix for this issue?
