Forms Completion Using Windows Authentication?
Apr 6, 2009
I 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.

We 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.

I 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:

I 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...

how 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()).

I'm writing an internal web application right now (with ASP.Net Web Forms), and it presents an odd problem. I have to be able to impersonate the currently logged in windows user, and execute a command based on their Windows Authentication to log in.. AND ... if they don't have Windows Authentication set up in the application I have to use to log them in, I have to be able to accept a user name and password. I also have to write the application in .Net 4.0, and secure it as much as possible. I got this to work by NOT utilizing Windows Authentication or Forms Authentication in the web.config, and instead setting session variables to guard against user accessing pages in the web app other that the log in. I did this by creating an oddly name session variable with a value based on their user name (windows auth or not), and then a secret session variable. The secret variable is in the web.config as a 256bit encrypted string, in which I decrypt, and set as the session secret. In order for the page to load, the first session variable can't be blank, and the second variable has to equal the decrypted key value... if the variables don't pass inspection, it redirects them to the login page. I set this up on every page, generic handler, and webservice method in the web app. I make the session timeout after a few minutes of no activity, and on log out, I set all session variables to nothing, and expire all cookies. (I also disable all cache).
My question is... Does this offer comparable security to that of Forms authentication? I have always used Forms authentication, but can't use it here. If I did, the users would have to reconfigure settings in IIS and in he web.config to toggle login procedures (From my knowledge, you can't use both Forms authentication, and windows authentication to manage the security of your pages and other web resources). With the method described above, I can accomplish the best of both worlds, but am curious about the security of my methods. Is there anything else I can implement here to assure the utmost security other that using forms authentication? Is it possible to accomplish the same level of security of Forms authentication without using it?

I 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.

I am working on a windows application and I am developing application using VB.Net. I want to create one form for Username and password and I want to create a table in database which will contain all the user details with UID and Password. So I am planning to use either Windows authentication or SQL authentication on database side for allowing user to connect database with my application But I am curious to know the best practices which are widely used across. Can anyone share the blogs,articles or your own experiences.

?_dsEntry.NativeObject
A first chance exception of type 'System.DirectoryServices.DirectoryServicesCOMException' occurred in System.DirectoryServices.dll

On the server, I get my current logged-in username, but from a remote client I get server name/administrator.
Below is the code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Grab username from Windows Authentication, remove the 'HHI', and assign to empName
'empname = Replace(HttpContext.Current.User.Identity.Name.ToUpper, "HHI", "")
'empname = Replace(Page.User.Identity.Name, "HHI", "")
[code]....
I've tried Application Pools with 'Network Service', with Named Accounts and setting the pipeline mode to 'Integrated' and 'Classic'. The above code works properly in Server 2003/IIS6, but I haven't been able to make it work on Windows Server 2008R2/IIS 7.5.

I buit a ASP page that gets the users information who is logged into the computer ie username etc. This was using IIS6 Now I've moved over to IIS7 on Server 08, I set it up to use "Widows Authentication", however when i run my ASP.NET Page it uses the account NT AUTHORITYNETWORK SERVICE to do its work.Ive looked all over online, and cant find a way to fix this.I just want to pass the user credetials from logging into the computer, to the web.I've made sure that I have this in my web.config
<authentication mode="Windows"/>
<identity impersonate="true"/>
When I run this the site from Visual Web Developer and it creates the site, it pulls back the correct information.However, when I Then to my browser and check this and it dosent pull back the correct account, it pulls back that NT account.etc. but it always seems to pass the same wrong account NT AUTHORITYNETWORK SERVICE it should be my accountname I am logged in with.

I have an issue with my .NET application and it can only be reproduced sometimes and only on client's location, which makes it extremely difficult to resolve. In the application the forms authentication is used. There is a login page to which every anonymous user is redirected. After user enters username and password, it redirects to DefaultURL or some predefined page. The problem is that sometimes when user enters correct username and password, it doesn't login, instead it just refreshes the login page without any error messages. After several tries of inputing username and password, user is able to login to the system.
See my login page Submit_Click code below:
Dim userName As String = tbUsername.Text
Dim password As String = tbPassword.Text
Dim returnUrl As String = Request("returnUrl")

I 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.

Our 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.
