I've tested activesync with this tool https://store.accessmylan.com/main/diagnostic-tools , all is OK ! I will be able to put my front-end squid proxy for exchange 2007 in production soon ! -----Message d'origine----- De : Clem [mailto:clemfree@xxxxxxx] Envoyé : jeudi 22 mars 2012 14:40 À : 'Clem'; 'squid-users@xxxxxxxxxxxxxxx' Cc : 'Amos Jeffries'; 'squid-users@xxxxxxxxxxxxxxx' Objet : RE: TR: https analyze, squid rpc proxy to rpc proxy ii6 exchange2007 with ntlm Forgot the powershell command : get-outlookanywhere | set-outlookanywhere -IISauthentication basic,Ntlm Infos there : http://marckean.wordpress.com/2009/02/06/exchange-2007-sp1-outlook-anywhere- ntlm-authentication-for-domain-based-and-workgroup-based-computers/ -----Message d'origine----- De : Clem [mailto:clemfree@xxxxxxx] Envoyé : jeudi 22 mars 2012 14:32 À : squid-users@xxxxxxxxxxxxxxx Cc : Amos Jeffries; squid-users@xxxxxxxxxxxxxxx Objet : RE: TR: https analyze, squid rpc proxy to rpc proxy ii6 exchange2007 with ntlm Hello all I'm glad to inform you that's I have found a workaround solution for outlook anywhere client via NTLM. I really didn't want to change any config of my clients outlook, who are actually configured on NTLM auth via Outlook RPC Proxy settings. Outlook Anywhere is configured in NTLM. Recently I have found that the main problem with squid was the double hop NTLM. So I though a different way : NTLM Clients credentials -> SQUID -> Basic Squid Auth -> IIS RPC PROXY -> NTLM client Credentials carried by squid -> Outlook Anywhere And that works !! The trick is to enable both "Integrated Windows Authentication" (NTLM) AND "Basic authentication" on the Rpc virtual directory of IIS (6 for my own). On Squid you have to use login:DOMAIN\user:password to send a credential that can auth (I have used Admin one). Dunno if it's secure to use AD admin user/pass directly in squid.conf ? Anyway that works so I'll continue to test now with that config. Now I've to test activesync with Iphone, and after with my Blackberry Server Express. I can paste you some of my configurations if you need Regards Clem -----Message d'origine----- De : Guido Serassio [mailto:guido.serassio@xxxxxxxxxxxxxxxxx] Envoyé : dimanche 18 mars 2012 12:36 À : clemfree@xxxxxxx Cc : Amos Jeffries; squid-users@xxxxxxxxxxxxxxx Objet : R: TR: https analyze, squid rpc proxy to rpc proxy ii6 exchange2007 with ntlm Hi Clem, Currently it seems that a fully working reverse Proxy Open Source solution for Exchange 2007 and 2010 is not available. Squid is really near to be fully functional, but there are still some problems. Look my comments in this bug: http://bugs.squid-cache.org/show_bug.cgi?id=3141 Currently I'm running a patched Squid 3.1.19 with http 1.1 support enabled in front of a Exchange 2010 Server. RPC over HTTPS seems to work fine, while EWS from Apple and BlackBerry clients is still problematic. I have tried also to use 3.2, but things seems to be worse: RPC doesn't work at all.
