    <p>I have a office plugin that connect a service using <code>HttpWebRequest</code>.</p> <p>Inside a domain I pass <code>CredentialCache.DefaultNetworkCredentials</code> so all is fine. Outside a domain a user need to provide username, domain and password. This don't work atm.</p> <p>Some part of the code out of it:</p> <pre><code>CookieContainer cookies = new CookieContainer(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = WebRequestMethods.Http.Post; request.AllowAutoRedirect = true; request.CookieContainer = cookies; // provide session cookie to handle redirects of login controller of the webservice if (isWindowAuthentication) // isWindowAuthentication is set earlier by config { if (Common.UserName.Length &gt; 0) { string[] domainuser; string username; string domain; if (Common.UserName.Contains("@")) { domainuser = Common.UserName.Split('@'); username = domainuser[0]; domain = domainuser[1]; } else { domainuser = Common.UserName.Split('\\'); username = domainuser[1]; domain = domainuser[0]; } NetworkCredential nc = new NetworkCredential(username, Common.Password, domain); CredentialCache cache = new CredentialCache(); cache.Add(request.RequestUri, "NTLM", nc); request.Credentials = cache; } else { request.Credentials = CredentialCache.DefaultNetworkCredentials; } } </code></pre> <p>Later on I do the request <code>request.GetResponse();</code>. If I use <code>CredentialCache.DefaultNetworkCredentials</code> then everything works fine. The moment I switch to my own <code>new NetworkCredential()</code> part the authentication fails.</p> <p>I checked the logs of the Apache (it is Apache 2.2 using SSPI mod). When it succeed the first request redirect to the login controller, then the login controller request credentials. Passed and works (redirect to the target site).</p> <p>Log 1 (works):</p> <pre><code>192.168.14.9 - - [25/Oct/2012:11:35:35 +0200] "POST /ror/ioi/start?document%5Bguid%5D=%7Be3d8f1de-10f2-4493-a0c0-97c2acb034e6%7D HTTP/1.1" 302 202 192.168.14.9 - - [25/Oct/2012:11:35:35 +0200] "GET /ror_auth/login?ror_referer=%2Fror%2Fioi%2Fstart%3Fdocument%255Bguid%255D%3D%257Be3d8f1de-10f2-4493-a0c0-97c2acb034e6%257D HTTP/1.1" 401 401 192.168.14.9 - - [25/Oct/2012:11:35:35 +0200] "GET /ror_auth/login?ror_referer=%2Fror%2Fioi%2Fstart%3Fdocument%255Bguid%255D%3D%257Be3d8f1de-10f2-4493-a0c0-97c2acb034e6%257D HTTP/1.1" 401 401 192.168.14.9 - rausch [25/Oct/2012:11:35:35 +0200] "GET /ror_auth/login?ror_referer=%2Fror%2Fioi%2Fstart%3Fdocument%255Bguid%255D%3D%257Be3d8f1de-10f2-4493-a0c0-97c2acb034e6%257D HTTP/1.1" 302 156 </code></pre> <p>The own credential results here Log 2 (do not work):</p> <pre><code>192.168.14.9 - - [25/Oct/2012:12:05:23 +0200] "POST /ror/ioi/start?document%5Bguid%5D=%7B6ac54e8a-19f1-4ccd-9684-8d864dd9ccf7%7D HTTP/1.1" 302 202 192.168.14.9 - - [25/Oct/2012:12:05:23 +0200] "GET /ror_auth/login?ror_referer=%2Fror%2Fioi%2Fstart%3Fdocument%255Bguid%255D%3D%257B6ac54e8a-19f1-4ccd-9684-8d864dd9ccf7%257D HTTP/1.1" 401 401 </code></pre> <p>What I don't understand is when I inspect e.g. <code>CredentialCache.DefaultNetworkCredentials.UserName</code> then is is empty.</p> <p>Anyone know what to do and how I have to set my own credentials correct that the authentication works as expected?</p>

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.
