Is there a way to force Opera to support Integrated Windows Authentication?

I use Opera as much as I can at home and at work, but my employer is moving as much as they can into Sharepoint. Their sharepoint configuration uses Integrated Windows Authentication, which attempts to check for valid credentials through IE, and if that fails it prompts for user/password. At least, that's what it's supposed to do. It's not a standard, exactly, but it functions in Safari, Chrome, and Firefox--they all prompt me for a username and password combination. Opera, however, gives me a:

The server requested a login authentication method that is not supported. Check that the address is spelled correctly, or try searching for the site.


error. I'm not sure what's going on, but if I had to guess, Opera is erroring on the initial attempt to determine credentials, and isn't failing over to the standard username/password authentication.

Normally I'd just use another browser for Sharepoint, but lately I haven't been using Opera very much at all.

Is there a way of configuring Opera to correctly handle integrated windows authentication?

I'm on OSX 10.6.8 with Opera 11.11 build 2109. This also happens with Opera Next (12.00 pre-alpha 1085 with a clean profile).

Opera supports the Windows specific NTLM and Negotation authentication methods, but only for versions running on Microsoft Windows, since we are using the Windows APIs to perform the operations; for natural reasons those APIs are not available on other platforms (if equivalent APIs are available, we would appreciate being corrected).

Is there any possibility for a work around, it would be greatly appreciated because its quite annoying having to change browsers every 5 minutes.
I have the same problem because my uni login uses a similar system to login so I need it all the time.

So yngve, I take your statement to mean that if it's an Apache server that won't work?

It's hugely frustrating to me that every other browser has managed to solve this problem. Clearly it's possible.

What I was talking about was the platform Opera runs on.

Yeah, rereading that makes sense. Thanks.

This issue was a mac issue. Opera on mac doesn't have access to a library that would let it understand Windows authentication, like with sharepoint. It's just apparently something Opera can't do. Yes, the situation sucks.

Basically, you need to use a different browser to access anything that requires windows authentication. :-( There is no workaround at this time.

Um... maybe I'm misunderstanding what you are saying.

Safari, Firefox, and Chrome are all able to successfully access our intranet on Macs. It's only Opera (only on Macs) that gets an error, and I suspect it gets the error because it is not falling back to a different (non-Windows-authentication) method as the other browsers are.
