The solution was to change the user agents to the style "Mozilla/5.0 ($OS) mirall/x.x.x". After that, the proxy happily accpted basic auth.<div><br></div><div>This way, at least the Windows client will work. I was willing to make that sacrifice because I am aware of at least one mobile ISP that checks for user agents (of course the real fix is to encrypt your traffic with SSL, but some choose not to). I am not willing to hardcode "Windows" though when its not (Linux, OS X). This makes debugging hell ("What, you are using Mac OS? The server logs indicate you are using a Windows client!").</div><div><br></div><div>IMHO, User-Agent filtering is even more retarded than blocking ports (claim to fame: all modern malware is using port 80 today, making it even harder to detect), but at least that makes ownCloud client work in a "slightly paranoid default corporate setting".</div><div><br></div><div>Daniel</div><div><div><br><div><div>Am 29.05.2013 um 10:37 schrieb Marcos Mezo:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>I'm just a follower of the mailing list and testing OwnCloud myself for a few months, so no expert here.<br><br>From what I see ,you are using a proxy and when using the web browser it validates "automagically" with NTLM.<br><br>As far as I know, but maybe things have changed, with client version 1.2 onwards proxy auth is supported, but only with basic authentication, not with NTLM.
