Exchange + Reverse Authentication + Logout

Hi,

we are running Exchange 2013 SP1 and are using our Sophos UTM as WAF. We also use the reverse authentication feature to handle logins completely through the UTM before passing the user to the Exchange OWA.

While setting this up was quite a task, it now works pretty well - with one exception. After setting the Exchange Server to Basic authentication (which is a requirement for reverse auth), the "Logout" button within OWA only displays a small popup "Please close all your browser windows now". See the attached screenshot for this.

But the user is not really logged out upon clicking the button.

Forefront TMG had a feature to specify a specific logoff URL which was used to logout the user. They probably "hacked" this URL into the exchange OWA while doing the proxying - but thats just a rough guess.

Is there some way to get an real "Logoff" done using Exchange 2013 + UTM with reverse auth?

Thanks for your support,
Philipp

Thanks for explaining the issue, guys. Did you get Sophos Support involved, lightxx? They have very capable pre-sales engineers and they can access the developers fairly easily.
