MS CRM 2011 AD web service authentication using Soap issue RRS feed

  • Question

  • Hi,
    May i know how do we authenticate to MS CRM 2011 web services?

    I am using Lotus script to do the web services which is similar to VB script language.
    I was using the 2007 end point URL and now i want to switch to the 2011 web services (XRM Services).

    WebServiceURL = CRMURL+"/XRMServices/2011/Organization.svc/web"

    SOAPAction = "http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Execute"

    Set objXMLHTTP = CreateObject("MSXML2.ServerXMLHTTP.6.0")
    Call objXMLHTTP.open ("POST", WebServiceURL , False,UserName,Password)
    Call objXMLHTTP.setRequestHeader("Content-Type", "text/xml; charset=utf-8" )
    Call objXMLHTTP.setRequestHeader("SOAPAction", SOAPAction)
    call objXMLHTTP.send(WebServiceRequest)

    The above code is used to authenticate with the 2007 end point URL and is working fine, But it is not working for the 2011 URL.

    I am getting the Authentication failed Response as shown below when i tried the 'WhoAmI' request

    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><s:Fault><faultcode xmlns:a="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-

    1.0.xsd">a:FailedAuthentication</faultcode><faultstring xml:lang="en-US">Access is denied.</faultstring></s:Fault></s:Body></s:Envelope>

    I guess the username and Password should set in some other way for crm 2011?
    Can anyone help me?

  • As you are not adding this as a web resource in CRM and it isn't a C# app your best bet is to look at this reference http://msdn.microsoft.com/en-us/library/gg327838.aspx.

    More then likely you cannot use the /web on your service url as this is for internal webresources accessing CRM services.

    This also describes the /web limitation/internal auth feature. http://msdn.microsoft.com/en-us/library/gg490657.aspx

  • Thanks to both of you for the Reply.

    I thought web services using external Soap Application can be done only by using the  /web part and i saw the same in some blogs.

    In regards to the authentication issue, Some one told me you can try to not authenticate at all. The Dynamics CRM is a single sign on application so the windows platform is handling authentication for you. 

    we need non windows user to authenticate with CRM  using our application as well , In that Case we have to authenticate  with CRM with a specific username and password.

    That's where we are stuck. 

    He also mentioned to authenticate with 2011 AD, you have to use the WCF Service. I don't have an Idea about the WCF service.

    Do you know whether is that something that can be done using SOAP/XML request and authenticate with CRM?
