Windows Form Application Windows Authentication
Apr 30, 2010I have a VB.Net project that I am running from a local server and I need to use the credentials the user is currently logged in with to upload a file to a folder I create on a SharePoint site on the same domain. I can get it to upload if I specify the credentials but it will not work with system.net.credentialcache.defaultcredentials. It just gives me 3 empty strings and I get a 401 unauthorized error. I have seen a few threads that say you cannot use it with Windows Forms Applications. Is this true? Here is my code:

View 2 RepliesC# - Windows Authentication In .NET?
Feb 1, 2012I have a .NET application (mix of C# and VB.NET) where I would like to display a Windows Login Dialog box (or my own dialog box) and authenticate the user using Windows Authentication. Per requirement, I need to ask the user to authenticate after AT LEAST a minute of being idle. I would prefer a .NET native way of doing Windows Authentication but interested in other ways...
View 2 RepliesUse Windows Authentication In WPF?
Oct 5, 2009how to use Windows Authentication in a WPF app. I wouldn't have thought that it would be any different than in any non-WPF app, but it seems that it is. I want to go into my project Properties -> Application and ensure that Windows Authentication is on, but that option is not available in a WPF app (as the following document confirms).

If I ignore all that and just look at My.User.Name (VB), it is empty. This tells me that somehow Windows Authentication is not enabled.My plan is to use a PrincipalPermission attribute to restrict access to certain parts of my app (or perhaps the entire app, by applying it to Application_Startup()).

View 3 RepliesAdd Windows Authentication To Application
Jun 28, 2011I have a application that prints labels on a community computer.I would like to add a Windows authentication login form to allow any of our employees to access a configuration screen.The request would bring up the login form if the login passed (meaning the username / password was correct) the configuration form would open.Otherwise the user would just get a warning Msgbox.So far all of the examples I could find either apply ASP.NET or use the logged-in user. Not for additional access as I'm trying to do.

.net - Mvc Windows Authentication Allow All Users From Domain
Dec 8, 2011I have an mvc intranet application using windows authentication. It currently has one controller with three actions.
The first action (index) should be available to everyone, this is no problem. The second and the third actions should only be available to users in a specific DOMAIN. However the tag only gives me 2 options: Roles or Users. I tried using Users and setting it to 'DOMAIN*' and 'DOMAIN?' but that doesn't work.
C# - Use Authentication In 'Forms' And As Well In 'Windows' For A .net Web Application?
May 14, 2011We have an application in Access for UI and MS Sql server as Database server. We now decided to build a new application in web application for UI. This web application is only used by the employees who work for the company. But later we decided to host this web application on outside server. So the user (from this company only.) can able to login anywhere in the world. First I thought creating the web application using 'windows' authentication thinking we may be using it as an intranet web application. But now my manager asked me to use both 'Forms' and as well as 'Windows' for using this application and this web application will be hosted on outside server. I really don't catch his point of using both types of authentication.

View 5 RepliesForms Completion Using Windows Authentication?
Apr 6, 2009I am reading the article at: [URL].. Forms Authentication in ASP.NET 2.0". I am using VS 2008 and .Net Framework 3.5. I don't know if this makes a difference, so please let me know.
A user logs on to our system in the morning Based on their Windows Authentication, they can access several intranet applications. For a particular application, the user has to select their Organization or Position or Location.
Based on the user's Windows Authentication, once the user selects one of the three above and clicks a "Submit" button, a second page is launched that shows certain information about the selection based on the User's authentication.
For example, if User selects Organization, the following information will be returned based on the Organization THEY are a member of. They can not access information from OTHER organizations, ONLY their own based on their login credentials. This information returned as a result of the dropdownlist selected value includes: street address, city, state, zipcode, Bus. Unit #, etc. appears in labels on the second page.
The labels can be dynamically created at runtime. (I dont know if a User control can be created to do this, since the "Position" and "Location" will contain the same address information, and it doesn't matter at the moment). I just want to populate the labels on the second page (or on Postback) based on the User's log in credentials after they click the "Submit" button. Or, if they don't have to click a button, just have the information complete based on the selected value of the dropdownlist control.

View 5 RepliesLog Into Application With Windows Network Authentication?
Jul 22, 2011Our company runs Windows Server 2008 R2 and as part of the normal login procedure you type your username and password. IT sets the domain when you get your PC so that is all good. So, when you open IE, the intranet sight detects that you are person XXX YYY and then logs you into the site automatically as the right person.
Now is there any way that I can do the same with an application written in C# or VB.NET. I.e., I would like the user to not have to log in as they have already done so during Windows log in, and then use the application as the individual user. This is for loggin purposes and specific rights for each group.

View 1 RepliesUsing Aspnet_regsql.exe To Set Up Windows Authentication On An Already Matured Database?
May 14, 2009I have a database (using Microsoft SQL Server Management Studio Express) that is currently being used quite heavily in a functioning application. I am porting this application over to Windows Authentication rather than the current basic authentication system (or lack thereof) that exists.The easiest way that I know to set this up involves using the aspnet_reegsql.exe file to set up some tables for me. This obviously creates its basic tables, such as dbo.aspnet_Roles, dbo.aspnet_Users and dbo.aspnet_UsersInRoles.In the current database, there exist tables named dbo.Users, dbo.UserRole, and dbo.UserRoleMapping. Many of the stored procedures that are written currently for this database rely on these tables.

View 1 RepliesWindows Authentication For Intranet Users At The App Level?
Aug 16, 2011My company uses ActiveDirectory, and naturally the IT department wants to maintain control over it and not give control to other users. I'm developing an ASP.NET app (for internal use only) using an SQL Server 2008 database.My question is, how can I BEST use the .NET namespaces and SQL Server to manage access to the app within the organization at the application (or possibly DB) level? I would like the user to be authorized based on their network username as provided by ActiveDirectory.On a side note, I would also like to access their AD contact information.
From my understanding I can use the ActiveDirectoryMembershipProvider class or Domain Services in the System.DirectoryServices namespace. There's also LDAP which apparently is another possibility. I'm having a hard time making sense of it all, and much less which is the best option and how to implement it. Can anyone provide me with some direction and possibly some simple sample code?
