How do I use the Windows Token role provider for ASP.NET role authorization in WCF?

Hi Dinesh,

You may want to use WindowsPrincipal permission on your contracts for security.

[OperationContract]
bool Read();

[PrincipalPermission(SecurityAction.Demand, Role = "Authors")]
[OperationContract]
bool Write();

To utilize Windows Active Directory groups, configure a service behavior:

  
    
      
         principalPermissionMode="UseWindowsGroups" />
      
    
  


Here is the article that you may want to go though.

Hope this helps you.

Thanks.
