The HTTP request is unauthorized with client authentication scheme 'Anonymous'. consuming wsdl file

Question

I am trying to consume a wsdl file and get a soap response but I always get the error

The HTTP request is unauthorized with client authentication scheme 'Anonymous'.The authentication header received from the server was 'Basic Realm’=myrealm. The remote server returned an error: (401) Unauthorized

Here is my wsdl file

Here is the call I make

rmt_ws client = new rmt_wsClient();
                using (rmt_wsClient rmt_wsClient = new rmt_wsClient())
                {

                    ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

                    rmt_wsClient.ClientCredentials.UserName.UserName = UserName;
                    rmt_wsClient.ClientCredentials.UserName.Password = Password;

                    string messageToSend = "<wsTin>" + wsTin + "</wsTin><wsUser>" + wsUser + "</wsUser>" +
                        "<wsPswd>" + wsPswd + "</wsPswd><contain><bmrn>" + bmrn + "</bmrn><blrn>" + blrn +
                        "</blrn><bcnt>" + bcnt + "</bcnt><bafm>" + "bafm" + "</bafm></contain>";

                    rmt_wsClient.Open();

                    string responsed = rmt_wsClient.remittanceXml(messageToSend);
                    rtn = responsed;
                }

I saw in similar questions that there is something that I must change in app.config but everything I tried so far give me the same result.

Here is the part in my app.config in WcfClinet that I use now

<customBinding>
        <binding name="rmt_wsBinding1" >
          <textMessageEncoding messageVersion="Soap11" />
          <httpsTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"/>
        </binding>
</customBinding>
 <client>
<endpoint address="https://www1.gsis.gr/wsicispay/rmt_ws" binding="customBinding"
        bindingConfiguration="rmt_wsBinding1" contract="IcisPayments.rmt_ws"
        name="rmt_ws" />
    </client>

and here is the app.config in my main program that I make the call

 <basicHttpBinding>
<binding name ="rmt_wsBinding1">
          <security mode="TransportWithMessageCredential" >
       <message clientCredentialType="UserName" />
    </security>
        </binding>
      </basicHttpBinding>
    <client>
 <endpoint address="https://www1.gsis.gr/wsicispay/rmt_ws" binding="basicHttpBinding" bindingConfiguration="rmt_wsBinding1" contract="IcisPayments.rmt_ws" name="rmt_ws" />
</client>

I don't know if I must change the app.config in my WcfClient or there is another error. This is my first time I use wsdl files and soap messages. I don't have any details on how the server that I try to connect works.

Answer 1

For anyone who has the same problem. The main problem is that even when I send the credentials it doesnt send them as header. I found the answer in my previous part of the question here thanks to H.G. Sandhagen
