I do not see the issue with doubling message, but see 2 different MACs which use the same voucher

That isn't normal
I'll investigate this. Thanks for reporting it

The bug reported by Constantine happens when "Add MAC addresses as pass-through" is checked but "include username in created MAC" is not

This is an issue related to a confusion between these two captiveportal settings
If "include username in created MAC" is unchecked then the username linked to the pass-through is still saved as description but not saved in captiveportal config, meaning pfSense cannot compare this MAC to an username later.
This issue is not linked to the recent changes, but it is still a bug.

I would suggest to automatically include username in the created pass-through, both in the description and in config

Working fine for me with vouchers & with Authentication Server

This issue can be marked as resolved !
