I'm stuck with accessing to OTRS web services (via SOAP) from .NET application. I have OTRS installed over Apache/2.2.22 (Linux/SUSE) with Active Directory integration to authenticate users. I used WSDL файл from OTRS github to create needed classes to access OTRS web services. Then I create app.config (in attache app.txt) to connect to OTRS. A added small peace of test code:
Code: Select all
public class Test : OTRS_WebService.GenericTicketConnector_InterfaceClient
{
}
class Program
{
static void Main(string[] args)
{
Test tst = new Test();
OTRS_WebService.OTRS_SessionCreate sc = new OTRS_WebService.OTRS_SessionCreate();
sc.ItemElementName = OTRS_WebService.ItemChoiceType8.UserLogin;
sc.Item = "soap"; //Login to access SOAP
sc.Password = "1234567"; //Password to access SOAP
var rsp = tst.SessionCreate(sc);
}
}Message: "The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Negotiate'."
Inner exception: "The remote server returned an error: (401) Unauthorized."
If transport security is "Windows", then error message: "The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate'."
In Fiddler i see, that application send:

Content-Type: text/xml; charset=utf-8

Response is:

Then next request in Fiddler is:

and response:

This server could not verify that you are authorized to access

You either supplied the wrong credentials (e.g., bad password), or your

and that's all.
I tried to change app.config file in different ways, but there is no success.
