First, apologies if this isn't in the right group, but it kind of spans. I'm working with a client that has Windows Server 2003, WSS, accessed through a custom application. In this application, we need to attach files to cases by adding them to a database and storing them in Sharepoint. This process works fine at our office, but the client is having authentication problems.
The only authentication being used is Windows security. Before, my Sharepoint code (in C#) was in a file, and the users would get a login prompt. However, even if they entered correct information, it would not let them in and eventually give an Unauthorized (401.1) error. I decided to move the functionality to a web service and use the Credentials object to set up authentication. These are the calls in my web page:
pmdtc_ws.CreateSite svcCreateSite = new PMDTC.pmdtc_ws.CreateSite();
svcCreateSite.Credentials = System.Net.CredentialCache.DefaultCredentials;
string strResult = svcCreateSite.AttachFile(subWeb, sFileName, pFileContents);
And this is the web service's method:
public string AttachFile(string pFolderID, string pFileName, byte pFileContents)
SPSite site = SPControl.GetContextSite(Context);
SPWeb web;// = SPControl.GetContextWeb(Context);
string tmpSite = site.Url;
if (pFolderID != "0")
tmpSite += "/" + pFolderID + "/";
tmpSite = tmpSite.Substring(7);
int posSite = tmpSite.IndexOf("/");
tmpSite = tmpSite.Substring(posSite);
web = site.OpenWeb(tmpSite);
web.AllowUnsafeUpdates = true;
folder = web.GetFolder("Shared Documents");
file = web.GetFile(folder.Url + "/" + pFileName);
if (file.Exists) ////check in existing file
file.CheckIn(""); ////We have to force the checkin here.
else ////Add a new file
files = folder.Files;
files.Add(folder.Url + "/" + pFileName, pFileContents);
strMessage = "Success!";
catch (Exception ex)
strMessage = "Fail! " + ex.Message.ToString();
When I run this, I get back an ASP.Net error page, that says the user is unauthorized: 401, treating it as an unhandled exception. (As a note, users have Contributer permissions in Sharepoint, and a cross-site group with Contributer permissions is set up for the subsites that files might be stored to, but this happens at any level.)
We found that if the administrator does a file attach, it will work, and allow access to the site for a time, before it loses that access. Also, when I used a standard user (having the problem) to access the Sharepoint site, we got this error message:
List does not exist
The page you selected contains a list that does not exist. It may have been deleted by another user. Click "Home" at the top of the page to return to your Web site."
There was a fix mentioned on Google for this, giving users read access to the webtemp.xml file in Templates/1033/XML, but that worked only until we rebooted the machine.
I've been trying to figure this out for a few weeks now with no success, so any help would be extremely appreciated. Thanks.
