Re: Difference between asp.net development server and IIS (relating to web service calls)

Thanks - I've tried all that and it doesn't work.

I have tried using the default credentials and even hard coding my log in details into the credentials.

I have identity impersonate set to true. And I have windows integrated authentication turned on.

I still get this error (going through iis, not asp.net development server).

The authoriusation error is definately happening when I call the web service.

Any ideas?

Okay, I re-read your post.

As I stated, the ASp.Net dev server basically runs with an account with admin priveledges.

If you run in IIS even if you authentice, the application doesn't "run as" who you authenticate.

To mimic this enable impersonation.

Add this to your web.config:

<identity impersonate="true" />

Otherwise, adding the credentials to your proxy will add the anonymous ASP.Net's account to the proxy not the authenticated users.

I've often had problems with IIS when Anonymous and Integrated Authentication are on together.

The only surefire way to pass the credentials is with

proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

Does the client fail to connect to the web service or does something the service does cause an error?

The ASP.Net Development server runs all of your code under the credential of the person logged into the machine (the developer).

Do you have impersonation enabled on the web service project?

Yes - I've enabled Integrated Windows Authentication under directory security

Have you checked that your IIS is set to use Integrated Authentication?

Hello - If I call a windows authenticated web service from a web app running through the Visual Studio asp.net development server it works fine.

If I call the same web service from the same app running from iis, it fails.

I add the credentials of a windows account to the web service call.

Like I say - it works when running the asp.net development server but not under iis.

It's as if iis doesn't pass the credentials over but asp.net development server does.

Any idea how I can get iis to run the same?
