Web Service acces with authentication

Hello,

I tried to acces a web service from a C# application running on a pocketPC.
It only works if I enable anonymous acces in IIS authentication properties.
Otherwise I got the following error :

"Server found request content type to be 'text/html', but expected
'text/xml'."

The code I used look like this:

phws3001 phws3001WebService = new phws3001();

phws3001WebService.Url = GlobalVarsClass.sWebServiceURL;

phws3001WebService.PreAuthenticate = true;

// Set the client-side credentials using the Credentials property.

NetworkCredential myCred = new NetworkCredential(GlobalVarsClass.sLoginName,
GlobalVarsClass.sLoginPass);

phws3001WebService.Credentials = myCred;

string sData = phws3001WebService.SyncronizeData();


In a PC desktop applocation I should use the CredentialCache class in order
to work properly, but .NET Compact Framework doesn't support this class.

An embeddedVB 3.0 application using the same WebService and running on the
same pocket works ok, so it should work in C# either, I supose.

Any ideea ?

Thank you,
Alex
 
That means that the response to the web service call was actually an html
page, rather than a soap response. Unfortunately, there is no good way to
obtain the actual html page returned by the web server.

Mike, you are right . :-)
My exception is result my experiments with other ways for make auth
access to non Windows web services.

You're best bet here is to enable Basic or Digest authentication. When you
use Basic authentication, your password is transfered in the clear, whereas
for Digest authentication, your password is hashed, and is relatively
secure (against theft, replay, etc). IIS allows you to specify a specific
password when you use Basic authentication, and for Digest, you use domain
passwords.

In both cases, you can attach a NetworkCredential instance to the instance
of the web service proxy class (through the Credentials property). This
will cause the .net CF to authenticate the client to the web service.
