Question

I have WCF web-service with windows authentification.

Binding

<bindings>
  <netTcpBinding>
    <binding name="CommonWindowsBinding" maxReceivedMessageSize="40000000" >
      <security mode="Transport">
        <transport clientCredentialType="Windows" />
      </security>
    </binding>
  </netTcpBinding>

</bindings>

Endpoint

    <endpoint address="Windows"
              binding="netTcpBinding" 
              bindingConfiguration="CommonWindowsBinding" 
              name="MyNameSpace.Contracts.ISimplePluginServiceWindows" 
              contract="MyNameSpace.Contracts.ISimplePluginService">
      <identity>
        <dns value="WCfServer" />
      </identity>
    </endpoint>

I want to pass additional information to service for such authentification (I check auth by using checking MS SQL Server’s users and logins – I need to pass mssql server name and database name). So, I have to pass some custom data to validator => I have to make custom validator for Windows authentification. How can I do it? I couldn’t find any examples.

For UserName authentification, I can do it by using CustomUserNameValidator (pass server address and database name with login), which inherits UserNamePasswordValidator.

Answer 1

I realized, that it was commonly wrong approach.

1. I can authentificate to MSSQL server with current Windows user’s credentials from WCF service by using delegation – http://msdn.microsoft.com/en-en/library/ms730088.aspx

2. If it is nessesary to pass additional data (such as server name and db name), such action should be performed by using special method in service contract.
