Ok, if someone could shed some light on this for me, I would greatly appreciate it. So here we go. I had a rest service running fine the other day but after I accidentally overwrote the web.config all hell broke loose. I've spent the past day and a half trying to sort things out but I can't seem to figure out what is missing or misplaced.
So, I've designed this service around WCF Rest Contrib (http://wcfrestcontrib.codeplex.com)'s authentication process. Now, I can get this working fine on my localhost w/ the current web.config (minus the endpoint entry) but once I upload it to discountasp and select "basic authorization" in the ISS7 Manager, it appears that I'm getting authenticated twice! Once using my discount asp.net user/pass and then the next time using the application user/pass. Unfortunately I only provide one set
of credentials and don't want to hard code my discountasp account info into the app. Like I said before, this worked fine a few days ago. Anyway. here is my web.config as it is now:

So, whenever I upload this and change the ISS setting to Basic Authentication, it looks like it is trying to use the default handler for authentication as if I try to enter my web app user/pass, I get an error screen which has the following detailed information about the moduel/handler
Detailed Error Information
Module: IIS Web Core
Notification: AuthenticateRequest
Handler: svc-ISAPI-2.0
Error Code: 0x80070005
Requested URL: http://www.mydomain.com:80/MyService.../MyService.svc
Physical Path: E:\web\xxxxxx\htdocs\MyServiceBaseAddress\MyService.svc
Logon Method: Not yet determined
Logon User: Not yet determined
Now for the fun stuff... i tried providing my discountasp.net account username/password for kicks and sure enough it responded properly for any [OperationContract] which doesn't have [OperationAuthentication] defined (which is only one or two
of the operations I have).
I thought this was strange, so I looked at fiddler and saw something interesting.
Whenever I try request a procedure with [OperationAuthentication] defined and provide my discountasp.net username/pass I get two different "WWW-Authenticate" headers back in Fiddler:
WWW-Authenticate: Basic
realm="MyRESTServiceRealm"
WWW-Authenticate: Basic
realm="www.mydomain.com"
On the other hand, if I try to access the same procedures with only my application's user/pass, I only get the site's header:
WWW-Authenticate: Basic realm="www.mydomain.com"
My hypothesis is that for some reason I'm having to
pass through the default "Basic Authorization" layer set by IIS before I can get to the application's "Custom Basic Authorization" layer.
After verifying this by created an identical user/pass for my service that I use for my discountasp.net account, I was able to successfully
pass both layers
of authentication without any issues... so I think I can conclude that this is indeed the issue. Now how do I disable the default one? Do I need to do this in the IIS Manager, or in the web.config?
Anyway, I have absolutely no idea how this is possible or what I need to do to resolve the issue, but I know that something is seriously out
of whack.
Any suggestions would be greatly appreciated! Thanks.
