Using the "Name" we can achieve operational overloading
interface IInterfaceName
{
[OperationContract (Name = "aliasName1")]
int MethodName (int param1, int param2);

[OperationContract (Name = "aliasName2")]
double MethodName (double param1, double param1);
}

For authentication:-
Say windows,

set the authentication mode as follows
<authentication mode="Windows" />

then in the end point set bind the configuration as below.

<endpoint address="basic" binding="basicHttpBinding"
contract="WcfServiceLibrary1.IService1"
bindingConfiguration="BND" />

<bindings>
<basicHttpBinding>
<binding name="BND">
<security mode ="Transport">
<transport clientCredentialType ="Windows"/>
</security>
</binding>
</basicHttpBinding>
</bindings>

For to USE IIS,make sure that IIS Annonymous authentication
is DISABLED.
