OWA Reverse Auth problems

What do I need to configure on IIS, so the Reverse Authentication on OWA start working.
I have follow this guide:
https://sophserv.sophos.com/repo_kb/120454/file/Exchange%20WAF%20How%20to%209%202%20new.pdf

I have tried with LDAP (sAMAccountName), Active Directory,...
I simply cannot to login to OWA.

On OWA IIS directories I enable Basic Authentication (now, we have enabled Basic and Windows Authentication). On basic authentication I also configure Default domain.
I pass sophos Authentication, but then OWA returns Authentication PopUp. What to do?

Hi UniTM

Probably you are just doing it on the IIS side. You have also to make sure that the authentication is correctly configured on the exchange virtual directories (not only on IIS).

I found bug in Sophos.
If I put "prefix" domain.local then base64 forwarded string is
domain.localusername[:P]assword
between domain.local and username "\" missing, so I configure "prefix" like
domain.local\
and now authentication works.

UTM version. 9.309-3

Hi
I having the same issue when try to open the owa get the loging prompt back
Do you mean we should add domain.local\ to the property of the owa virtual directory?

Thanks
