Re: Apache reverse proxy x OWA authentication

Hello ,

I have success in reverse proxy to OWA/Exch2K with Apache2, but I have 
another problem: in some parts of OWA (specifically in pages that they 
require NTFS authentication), I receive the following message:
    Unknow authentication method.

I have too a https backend...

I search but I didnt find any solution, someone has some idea  ???

With best regards,

Fabiano
