os-OPNWAF / Exchange 2019 authentication Popups

[humnab]

Hello,

we're migration from a Sophos UTM to opnsense-business and try to replace the Sophos WAF with os-OPNWAF.
No we have the problem that we get authentication Popups in Outlook when we try to connect externally.
After canceling the popups or entering the password 2-3 times Outlook shows online.
When we do the same with the caddy plugin we have no popups (but no WAF), with the Sophos UTM WAF we also have no Popups.

Any idea whats wrong? The Web Protection is disabled in os-OPNWAF, the Locations are configured as "Exchange Server", the Remote destionatios with https://IP of Exchange...Thanks!

The popups should not happen since this apache plugin is compiled in:

https://github.com/opnsense/ports/tree/master/opnsense/mod_proxy_msrpc

Outlook Anywhere should just work the same as in Sophos (fun fact that module was developed by Astaro - which later became Sophos).

When I tested this while writing the manual, it was still working. Is your setup exactly as described? If not, do it like in the manual.
