    Credentials using Orian SDK




      I am trying to write a client app that consumes the SWIS web service. I am trying to login to the web service but when I execute the QueryXML method it throws an Exception:

      "Could not establish trust relationship for the SSL/TLS secure channel with authority 'solarwinds:17778'".

      I am guessing the web service is not able to authenticate the user credentials I am providing.

      I am setting the follwoing properties with no joy.

      client.ClientCredentials.UserName.UserName = @"mydomain\username";
      client.ClientCredentials.Windows.AllowNtlm = true;

      client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

      I was wondering if our administrators need to set my account up in Solarwinds differently or there is a configuration step being missed.

      I have access to the Solarwinds dashboard via the browser without logging in but my nt account credentials are not working for the webservice.

          There are two things going on here.

          First: the "Could not establish trust relationship" error you are getting is because the certificate SWIS uses for HTTPS is intentionally not a valid certificate. It is self-signed rather than issued from a proper certificate authority like Verisign, and its common name is CN=SolarWinds-Orion instead of whatever the FQDN of your server is. You will need to bypass certificate validation with a line like:


          ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, errors) => true;

          In this mode, HTTPS provides confidentiality and replay protection, but not host authentication.

          Second: unfortunately at this time SWIS does not support authenticating Windows accounts over HTTPS. This is something we are looking at fixing in a future release. Until then, you will need to use non-Windows Orion accounts for this API.
