    <p>I'm hooking into SSRS 2008's ReportingService2005 service via WCF.</p> <p>I have it working with impersonation, like this:</p> <pre><code>ReportingService2005SoapClient rService = new ReportingService2005SoapClient("endpoint config name", "the url"); rService.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation; rService.ChannelFactory.Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials; </code></pre> <p>But when I try and pass a specific username/password to it instead, like this:</p> <pre><code>rService.ChannelFactory.Credentials.Windows.ClientCredential = new NetworkCredential(username, password, domain); </code></pre> <p>I get this error on the first method call:</p> <blockquote> <p>The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'NTLM'.</p> </blockquote> <p>Here's the relevant part of my wcf binding config:</p> <pre><code>&lt;basicHttpBinding&gt; &lt;binding name="ReportingService2005Soap" ... blah blah blah ... messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;security mode="TransportCredentialOnly"&gt; &lt;transport clientCredentialType="Ntlm" proxyCredentialType="Ntlm" realm=""/&gt; &lt;message clientCredentialType="UserName" algorithmSuite="Default" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/basicHttpBinding&gt; </code></pre> <p>I'm confused by the error message mentioning Ntlm in two different cases.</p> <p>So the question is - which of the two squillion different WCF settings do I need to fiddle with to get this to work? : ) </p> <p>edit: here is the authentication bit from RSReportServer.config from the SSRS server:</p> <pre><code>&lt;Authentication&gt; &lt;AuthenticationTypes&gt; &lt;RSWindowsNegotiate/&gt; &lt;RSWindowsNTLM/&gt; &lt;/AuthenticationTypes&gt; &lt;EnableAuthPersistence&gt;true&lt;/EnableAuthPersistence&gt; &lt;/Authentication&gt; </code></pre> <p>and from the SSRS web.config:</p> <pre><code>&lt;authentication mode="Windows" /&gt; </code></pre> <p>edit: I'll mark the best answer so far for now, but this is still open because I havent yet found a solution that lets me set arbitrary credentials in code.</p>

    1. COThe error message suggests that this might simply be a casing problem - have you tried amending the binding to use `clientCredentialType="NTLM" proxyCredentialType="NTLM"`?

    2. CO@Ed: Yeah, tried that. If I use capitals I get error 'The value of the property 'clientCredentialType' cannot be parsed.'

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
