Passing security credentials to the third server

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :ASP.Net
I have the following scenario.  An user uses the desktop application to call our WCF Service which has windows authentication.  The WCF Service calls the Office Communication Server (OCS) in order to do some custom work.  When the WCF Service calls OCS we have to pass an instance of NetWorkCredential into the call.  I want to pass in the original calling users NetworkCredential object into the OCS call rather than constructing it using a custom username and password.  How do I get access to the calling users NetworkCredential object from the WCF service and pass it to the OCS call?ThanksArjuna.

Passing credentials from Sharepoint application to Reporting Server

Hi, Think of an environment where SSRS is deployed in share point integrated mode. There is a sharepoint application which is using user authentication (not windows authentication) for validating the login credentials of users using the application. There are some reports presented as web parts in the sharepoint application. Now, how should the user credentials be passed from Sharepoint application to Reporting services and how should they be validated? How the user credentials from sharepoint to be passed to report server and validate the permissions before showing up the report? Please let me know.  Phani Note: Please mark the post as answered if it answers your question.

Hackers Beware: Keep Bad Guys at Bay with the Advanced Security Features in SQL Server 2005


Get a peek at the new security features in SQL Server 2005 from a developer's point of view. While there are lots of admin enhancements, there are also plenty of dev-specific security improvements you can take advantage of, such as endpoint authentication and support for the security context of managed code that executes on the server. Here Don Kiely elucidates.

Security: Unify Windows Forms and ASP.NET Providers for Credentials Management


The .NET Framework 2.0 provides custom credentials management to ASP.NET apps out of the box. Using it, you can easily authenticate users without using Windows accounts. In this article the author presents a set of helper classes that let a Windows Forms application use the ASP.NET credentials management infrastructure as easily as if it were an ASP.NET application.

Intrusion Prevention: Build Security Into Your Web Services with WSE 2.0 and ISA Server 2004


Once you've addressed security in your code, it's time to look at the environment it runs in. Firewalls stop unauthorized traffic from getting into your network, and smart Web service-specific firewalls, like the one that comes with Internet Security and Acceleration (ISA) Server 2004, bring XML intrusion prevention to your system for that added layer of safety.

ISA Server 2004: Developing an Application Filter for Microsoft Internet Security and Acceleration S


The beta version of Internet Security and Acceleration (ISA) Server 2004 is now publicly available. It includes a rich SDK with several extensibility mechanisms that allow third parties to integrate their specialized solutions on top of the ISA platform. In this article, the author explores the application filter extensibility mechanism, which enables you to add high-level application layer filtering capabilities to ISA Server and to provide rich content filtering solutions. He also highlights the new features of the ISA Server 2004 SDK, then moves on to describe how to develop a basic application filter that monitors all data going through the ISA Server, and how to integrate a filter into the ISA Server management console to create a seamless interface experience for your users.

Windows Server 2003: Discover Improved System Info, New Kernel, Debugging, Security, and UI APIs


There's a lot to say about Windows Server 2003. First of all, it's the first operating system with built-in .NET Framework support, and it's the first 64-bit OS from Microsoft. But wait, there's more! There are lots of new features and APIs in this version as well. For instance, Windows Server 2003 features Hot Add Memory and a number of other arcane new tidbits. There are new APIs for handling threads, directories, and files, and new features like the low fragmentation heap for managing memory and system information. There's vectored exception handling and new UI APIs as well.OS internals expert Matt Pietrek takes a look at the additions he finds most interesting and useful so you'll have a good place to start when you dive into Windows Server 2003.

Security Briefs: Exploring S4U Kerberos Extensions in Windows Server 2003


Building Web sites that provide services external to the corporate firewall is tricky. Usually it's not desirable to grant corporate domain accounts to external clients, and from a purely practical standpoint Kerberos does not work well over the Internet due to the typical configuration of client-side firewalls.

Active Server Pages+: ASP+ Improves Web App Deployment, Scalability, Security, and Reliability


ASP has been rebuilt from the ground up. The result? Active Server Pages+. ASP+, with a host of new features, provides for easier to write, cleaner code that's simple to reuse and share. ASP+ boosts performance and scalability by offering access to complied languages; development is more intuitive thanks to Web Forms; and an object-oriented foundation facilitates reuse. Other important features include page events, Web Controls, and caching. Server Controls and improvements in data binding are also new with ASP+. Libraries for use with ASP+, and the Microsoft .NET Framework which allows custom business functions to be exposed over the Web, provide more new development opportunities.

TSQL: Passing array/list/set to stored procedure (MS SQL Server)

Passing array/list/set to stored procedure is fairly common task when you are working with Databases. You can meet this when you want to filter some collection. Other case - it can be an import into database from extern sources. I will consider few solutions: creation of sql-query at server code, put set of parameters to sql stored procedure's parameter with next variants: parameters separated by comma, bulk insert, and at last table-valued parameters (it is most interesting approach, which we can use from MS SQL Server 2008). Ok, let's suppose that we have list of items and we need to filter this items by categories ("TV", "TV game device", "DVD-player") and by firms ("Firm 1", "Firm2", "Firm 3). It will look at database like this So we need a query which will return us list of items from database. Also we need opportunity to filter these items by categories or by firms. We will filter them by identifiers. Ok, we know the mission. How we will solve it? Most easy way, used by junior developers - it is creating SQL-instruction with C# code, it can be like this List<int> categories = new List<int>() { 1, 2, 3 };   StringBuilder sbSql = new StringBuilder(); sbSql.Append( @" select i.Name as ItemName, f.Name as FirmName, c.Name as CategoryName from Item i inner join Firm f on i.FirmId =

Tips on using the SQL Server Security forum

I am collecting here a few tips on using this forum. The tips are actually pretty general, they're not really specific to SQL Server or to this particular SQL Server Security forum. 1.
