How to provide userid and pwd to a web service from a .NET client?

[Former Member]

I am trying to call a webservice on the ESOA located at sdn.sap.com and am getting an authorization error.

(Note: I am sure teh USERID and PASSWORD is valid).

Here is my Code

//Instantiate the web service

sap.CustomerERPSimpleByIDQueryResponse_InService sapService = new sap.CustomerERPSimpleByIDQueryResponse_InService();

//Define Login ICredentials cred = new NetworkCredential ("USERID", "PASSWORD");

sapService.Credentials = cred;

//Instantiate the parameters pass the the method

sap.CustERPSimplByIDQry_sSel selection = new sap.CustERPSimplByIDQry_sSel();

sap.CustERPSimplByIDQry_sProcgCond proccondin = new sap.CustERPSimplByIDQry_sProcgCond();

sap.CustERPSimplByIDRsp_sProcgCond proccondout = new sap.CustERPSimplByIDRsp_sProcgCond();

sap.NOSC_Log log = new sap.NOSC_Log();

//Select Customer with ID = "1"

selection.ID = "1";

//Call the web method

sapService.CustomerERPSimpleByIDQueryResponse_In(selection, proccondin, out proccondout, out log);

However when I tryo to call the web method, I get this exception:

System.Net.WebException was unhandled

Message="The request failed with HTTP status 401: Unauthorized."

Hi,

for SAP service:

NetworkCredentials cred = new NetworkCredentials("SAPUSER", "SAPPASSWORD");

service.credentials = cred;

for IIS service:

service.Credentials = CredentialCache.DefaultCredentials;
