Syncing Vouchers between one Master to many Slaves

[Chris-The-Tuner]

Hi together,
i remember a long time Ago there was a way if i was correct to sync Vouchers from one master to many slaves and back.

Problem is:
I run a dozen "Slaves" doing nothing more than providing a Captive Portal Gateway at some locations.
My goal would be to have one master instance where i generate the Vouchers and have all "Slaves" sync these so a Voucher would be effective on every Location in that System.

All "Slaves" connect to my main instance via OpenVPN.

Is there a way to get that to work ?

The High Avail Option i find seems to only be good for a 2 Node System as far as i understand.

@Gertjan that is a good idea in theory, but this would also mean that the voucher is not going to be "invalid" on all systems when used up in one.
