SSRS and "For security reasons DTD is prohibited in this XML document..." error HELP PLEASE!



I need some help here. We've had SSRS on our production server up and running for several months, after moving from another server that ran for a few years with no issues. Suddenly, 10 days ago we are getting this error, and I haven't figured out why.

1.     When rendering a report, we receive this message after a few seconds: “For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method.”


How to place security on a document library such that users only see documents they created?


When using lists, it is easy to specify that users can only see lists that they created (through Advanced Settings)... Is there a similar way to do this with document libraries? Rather than doing item level security... Thanks.

Working with SharePoint document libraries

Document libraries are collections of files that you can share with team members on a Web based on Microsoft Windows SharePoint Services. For example, you can create a library of common documents for a project, and team members can use their Web browsers to find the files, read them, and make comments. Users with Microsoft Office 2003 can check out and edit the files as if they resided on a local or network drive.

By default, your team Web site comes with a built-in document library named Shared Documents, which is listed on the Quick Launch bar as well as on the Documents and Lists page.

SharePoint Tutorial - Security

Security in SharePoint is comprised of users, groups and roles.

Users, Groups and Roles

A user account comes from the authentication system. For example, if Active Directory is used to authenticate then the user accounts will come from it.

There are two types of groups SharePoint uses: domain groups and SharePoint groups.

jQuery $(document).ready() and ASP.NET Ajax asynchronous postback

Many call it the ASP.NET jQuery postback problem, but using the technique below should make it no problem anymore. $(document).ready() isn't called after an asynchronous postback. What this means? You lose the functionality that should be executed within $(document).ready() after an UpdatePanel rendered its contents after an asynchronous postback.

SharePoint Document Workspaces for Developers

Office 2003 is being released this month, and a cast of supporting applications is already available. One of these is Windows SharePoint Services 2.0, the free team add-on for Windows Server 2003. If you're not familiar with SharePoint Services basics, take a look at What Developers Need to Know About Windows SharePoint Services. In this article, I'm going to drill into one key place where SharePoint and Office 2003 overlap: document workspaces

Upload a File to a SharePoint Document Library - Part I

The following helper class demonstrates a few techniques that allow documents to be uploaded to a SharePoint document library programmatically without using the API or a custom web service. You don't need to specify a document library name, and it will create any folders specified in the URL as required. File meta data will be updated if any properties are passed.

SharePoint document migration challenges when migrating files and folders

There are several challenges when migrating documents to Microsoft SharePoint. While these challenges can be overcome, they are a real pain if the migration source, content and file systems are not SharePoint friendly.

Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help. 

XBAP Security


We have a small XBAP file upload app that we are having trouble deploying. We were getting security errors when we were pushing this application that we don't get when running in our development environments on our machines. We gave the XBAP app full permissions and still got errors. Then we created a personal certificate and were able to get this to work. But that means we have to load a client side certificate for each and every machine that wants to run this which is ridiculous. Does anyone have a solution for this?

Intranet Users Challenged When Using Windows Integrated Security


We've setup an intranet site using Windows Integrated Security. Its up and running and users can access it. However, they are being challenged with a login dialog for the server when they initially access the site.

Isn't is possible to configure the server so that the users aren't challenged AND are recognized as being already authenticated by Windows? We're trying to go with a seamless experience, whereby all they have to do is login to their machine like normal and then go from there.

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).
