Windows Authentication For Intranet Users At The App Level?
Aug 16, 2011
My 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?
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.
I've got an app on server 1 that's attempting to copy files from server 2. Server 1 is 'quarantined' from the rest of the local network for security reasons, but the network guy has made a couple of server 1 directories available to server 1 via IP. Thus, in my VB.NET app on server 1 I am trying to do this:
Code:dim filearr as string()filearr = System.IO.Directory.GetFiles("\10.0.0.21packinglists", "*.pdf")
However, I want my app to run unattended and 10.0.0.21 requires a login and password. Can I configure a connection string or something to provide hands-off authentication?
I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.
I have an intranet asp.net application and when a page is loaded, i want to log the IP Address, Computer Name and the Windows Account(from active directory) currently logged into the computer from which the page is being accessed.
So far, Im able to get the IP address and computer name but the windows account, am getting NT AUTHORITYSYSTEM
How can an application, running on a production server, access the login username of the machine that a user is accessing an application from? For example, I am currently logged into my machine on the INTRA corporate intranet. My username will be INTRAUsername. I have added specific usernames to a database and wish to check this intranet username against the database to restrict access to an application and leverage the username across the application.Currently, I am using the following code to access the username:rivate username As String = Thread.CurrentPrincipal.Identity.Namehis is working great on localhost, but when authenticating against the database on a development server, I'm getting the following error:
I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
I am working on a windows application in vb.net 2005 and it needs to connect to the SQL Server database. In this example I testing if the connection is able to open properly:

Is it something dealing with the permissions set with the database server or something? I am new at .NET programming and I have been spinning my wheels on this for the past couple of days and I am at a loss. From what I research, this error should only occur if I was creating a web program, but I am not. It is a windows application.
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:
When I try to use Windows auth, the pop-up tells me: X website required login for Y domain.How can I hide the website name? And only show "You are required to login first" text on that pop-up?
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 want to use windows authentication in my c-sharp desktop application.where I cloud use windows create new users service and allocate local storage space.
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.
I write a dll some time ago that authenicated with a Windows Server 2003 Domain controller. Every thing worked fine. The IS group upgraded the domain controllers to Windows Server2008 R2 this weekend, now I can not authenicat anymore. It seems to have the correct LDAP path, when I get to the function that does the check for the user name i get the following error.
?_dsEntry.NativeObject A first chance exception of type 'System.DirectoryServices.DirectoryServicesCOMException' occurred in System.DirectoryServices.dll {"Logon failure: unknown user name or bad password. "}
I thought I had the command correct, but I wanted to make sure since I fail to connect in my app. Here is the connection command I use:New SqlConnection("Server=TestServer;Database=MasterDB;Integrated Security=SSPI")I have verified the server name, DB name, and that the server is using windows authentication.
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
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.
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.
Now that my application uses windows authentication to connect to the database, how will I authenticate the username and password that the user supplied? I've read about WindowsPrincipal and WindowsIdentity but still I have not found a way to do this.
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.
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.
i wrote a program that connect to sql server via a specify server name , user nameasswordim baby as new sqlconnection("server=baby;uid=sa;pwd=sa;database=baby")
I have the following code being used, it is really useless for me as I can't get much info using it, is there any other way I can save the info when a user logs in to store it for the whole time until the program closes?
