Error using membership in WCF

Postby y0zh » Fri 14 May 2010 08:47

Hello everybody. Sorry for my English.
I have a trouble using PgSqlMembershipProvider in WCF services for authentication.
My configuration section in web.config for service
Code: Select all





Code: Select all














When i call my method
Code: Select all
[PrincipalPermission(SecurityAction.Demand, Role = "admin")]
public string[] AdminMethod()                                      <- exception here

Code: Select all
I using proxy in my client (silverlight)

var proxy = new MyReference.MyServiceClient();
            proxy.ClientCredentials.UserName.UserName = "username";
            proxy.ClientCredentials.UserName.Password = "password";

I have an exception
System.Security.SecurityException was unhandled by user code
Message=Сбой при запросе разрешений для владельца учетной записи.(Failure at inquiry of permissions for the owner of the accounting record) (machine translate)

in System.Security.Permissions.PrincipalPermission.ThrowSecurityException()
in System.Security.Permissions.PrincipalPermission.Demand()
in System.Security.PermissionSet.DemandNonCAS()
in GISService.Authenticate(String UserName, String PasswordHash) в c:\Users\User\Documents\Visual Studio 2010\Projects\MyProject\site\App_Code\MyService.cs:string 590
in SyncInvokeAuthenticate(Object , Object[] , Object[] )
in System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs)

Why it occurs?

For Visual Studio 2010, the problem may be caused by the fact that the default hash algorithm was changed from SHA1 to HMACSHA256 in .NET Framework v4. We will set the hash algorithm explicitly in our code, the fix will be available in one of the nearest builds.

As a temporary workaround, please set the hash algorithm to SHA1 in ASP.NET providers of your application. For more information on this issue, please see the following topic:

If the problem persists, please send us a small test project with which the problem can be reproduced.
