Unable to execute web service with declarative security

[JediDan]

Hello all,

I'm trying to execute a web service in a C# windows app. Without any security provisions, it works fine. However, when we switch to declarative security, we get the following SoapException: "Server was unable to process request. -> Request for principal permission failed."

The web service code:

[WebMethod]
[PrincipalPermission(SecurityAction.Demand,Role="Manager")]
public string HelloWorld()
{
     return "Hello World";
}

The calling code in a Win app:

string[] sa = new string[2];
//sa[0] = "Employee";
sa[0] = "Manager";

GenericIdentity gi = new GenericIdentity("Dan");
GenericPrincipal pp = new GenericPrincipal(gi,sa);
System.Threading.Thread.CurrentPrincipal = pp;

webserver.WSTest myService = new webserver.WSTest();
myService.Credentials = System.Net.CredentialCache.DefaultCredentials;
			
MessageBox.Show(myService.HelloWorld());

Any help is appreciated.

Thanks,

Dan
