C# - Using Windows Authentication To Log In To A Sql Server?
Jun 4, 2010
I have a web application set up on our intranet that uses windows authentication (successfully) that I am trying to link to a database running on a separate server.
The problem that I am having however, is that when I try to use a trusted connection to log in to the sql server, instead of passing the domain/username of the person using the website the application is passing NT AUTHORITYANONYMOUS LOGON.
I checked that the authentication was working by having the website display a greeting that does identify my username correctly when I log on to the site, so it isn't an anonymous access issue. I think it is an impersonation issue somehow despite the fact that set in the web.config file for the application.
Curiously, the web application works fine when I run it on either my dev machine or even locally through remote desktop on the production server. I'm not sure what's going on here.
Finally, I'm running iis 7.5, windows server 2008 r2 and sql server 2008
I have just installed SQL Server 2005. I selected windows mode authentication. I am not able to login in management studion. Now, I want to use mixed and server authentication option inplace of windows authentication. so, would that be possible after installation.
This is a real quick question, is it possible to allow Windows Authentication for an ASP.Net intranet site (on a test server) to authenticate against the production server user accounts? If so, how would I go about doing so.
I have IIS 7 windows server 2008 R2 64 bit on which I have few web sites which are sending emails thorugh asp.net. Each web site has seperate "From Address (used inside the code)".
In IIS 6.0 mananger >> Delivery Tab >> Out bound security >>I gave Integrated windows authentication for one account (Let us say abc).
When the emails are firing from different applications, the emails are going only if the from address is abc mentioned in the authentication. If any other email address is used then it is going to bad mail folder saying "Diagnostic-Code: smtp;550 5.7.1 Client does not have permissions to send as this sender".So to make it work I have changed the authentication to anonymous then again the emails are going to bad mail with "Diagnostic-Code: smtp;530 5.7.1 Client was not authenticated" error.
I have a site on domain1. I need to open a ModalDialog with a Page on domain2. My Domain2 is protected not to allow anonymous access so i get a login window like:
My problem is, for this one functionality, i want users to be able to see that ASPX, through the ModalDialog, without authenticating.
I tried using the ftp way:(URL) and i get a javascript error.
My site is hosted in IIS6, Windows Server 2003 and i have full access to the server.
Just going to start making a web application and was wondering which was better, or at least what are the main differences between them (as it probably matters what I am using them for)?
i am using windows server 2008 and IIS , somebody installed Dynamic Business Portal everytime users trying to use the portal they enter the servername or by ip @ of the windows server /Bp but a login authentication asking them to insert a username and password they can t login the system even they enter their windows authentication
I published another new ASP called Mytest users put name of ther server or ip of the server /Mytest they were able to access the page and no pop up asked them or authentication I added IUser and Everyone and enabled full access.. i check the PB configuration in IIS it was the same Everyone and Iuser are added and full access is enabled how to get rid of the authentication popup
I have an ASP.Net app, that runs using windows authentication. The connection to the SQL Server is usually done by creating a sql server account and using that in the connection string.
However, in this specific very restrictive hosting environment, we have been asked to use a specific WINDOWS/active directory account to connect to the SQL Server.
note it is not the windows credentials of the user of the website, we need to connect to the SQL server with - it is one specific windows/AD account.
im using windows 7 home premium-64 bit,when i want to install sql server its not asking for mixed mode its directly creating windows authentication mode but i want to use sql server authentication mode,when im installing im unable to see any mode selection?
I'm using VS 2010 RTM and SQL Server 2008 on my clean development laptop, running Windows 7 Pro.
Using Visual Studio's Server Explorer, I can easily do an Add Connection by simply right-clicking, and then completing the dialog, and choosing "Use Windows Authentication". I can then click the button "Test Connection".
However, if I wish to do an Add Connection, and then choose "Use SQL Server Authentication", I get a message "Login failed for user 'appSlir'", as shown here:
When I try the same thing on my other development machine, which is VS 2008, SQL Server 2008, and Windows XP Pro, it works fine.
There seems to be a problem/bug that prevents Add Connection with "Use SQL Server Authentication" to SQL Server 2008, when running on Windows 7 Pro.
i have installed sql server express using windows authentication mode,but i have a doubt if we want to acces the data from front end we type like uid="",pwd="",servername="" but when using windows auth what credentials we have to give or there is no need of any details?
I have a requirement I should connect to MS SQL server under IIS Application pool account from ASP.NET application where Windows Authentication is enabled. I cannot use user name and password in connection string.
ASP.NET application should use Entity Framework 4.0 to work with data.
I set authentication mode to Windows in the web.config and I enable Windows Authentication and disable the Anonymous Authentication in IIS 7 on win 7, but HttpContext.Current.User is always null.It works fine when I host the web app in IIS 6.0.
I have been trying to avoid the windows login userid and password window when I use the Windows Authentication mode for a web site. I need to capture the the windows logon user name without prompting for the user id and password and display that on the web site. I had tried almost everything... changed authentication,security setups on IE and IIS etc... still not being able to avoid the window...
I'm trying to enable automatic Window authentication working on our ASP.NET Intranet. I've changed the Authentication on our IIS 7.5 server from Anonymous to Windows Authentication Enabled only, and changed the Web.config file for the website to:
The Windows login box appears when accessing the website via IE 8, I enter valid credentials, but the login window keeps reappearing as if it does not accept my credentials. By repeatedly cancelling the login box it disappears, and my login name can be viewed on the website. Is there any possible reason for the login box to keep popping up even though valid credentials are being entered? I've restarted the servers / cleared browser cache etc. Also, ideally I would like the user to enter the login details once in the login box and not be required to reenter login details whenever he reopens the browser.
I have a web application (intranet based) which uses Windows Authentication. Unfortunately there are public computers that have public logins at some company locations. My web app doesn't support these public logins because I need to know the user workingSo, even though these public users are windows authentication users, my app will fail because I have no user account setup for that particular account. I want to then try Active Directory Authentication.In my Default.aspx.cs I'd have something like this
protected void Page_Load(object sender, EventArgs e) {try userContext = new UserContext(); // If the authenticated user isn't a user in my system then throw an exception } [code]...
We have a working version of application (Intranet) with uses Windows Authentication deployed in Windows 2003. The application uses HttpContext.Current.User.Identity.Name to get the logged-in user. Here impersonate is turned off.Right now, we are move to Windows 2008 RC2 where this Windows Authentication problem arised. I have Digest Authentication and Windows Authentication enabled. And also I have enabled Anonymous Authentication enabled to avoid the Login dialog of IIS in the end-user IE. Now I am getting HttpContext.Current.User.Identity.Name as Empty. When I impersonate using username and password, I am used to login using that user but all the users uses the same user to login.Does any has solution for this?Deployment Server - Windows 2008 RC2 (IIS 7.5)Development - Windows 7 (IIS 7.5)I am new to IIS 7.5. Please give me a solution
My overall goal is just to get the logged on users information for an Intranet site I'm developing without them providing their login (since they are already logged into their computer). So far I just get 401.1 errors and it keeps asking for my login/password. Even though I provide my login/password, it still won't let me in.
I've Enabled Windows Authentication from IIS > Sites > Default Web Site, added this to my web.config:
I've been asked to convert an asp.net application from forms authentication with roles using the aspnetdb database to use windows authentication instead.
what is required to do this? can I still use the roles defined in the app and stored in aspnetdb?
I have an (ASP.NET 3.5) intranet application which has been designed to use forms authentication (along with the default aspnet membership system). I also store additional information about users in another table which shares its primary key with the aspnet_users table.
For users who are part of our domain I store their domain account name in the secondary users table, and I want to automatically log in users whose domain account name matches a name stored in the table.
I have read the guides which are available - they're all from two years ago or more and assume that you are able to activate Windows Authentication on a separate login page that allows you to extract the domain account name. From what I can tell, though, this is not possible in IIS7 (the overall authentication method is applied on all pages and cannot be selectively deactivated, and both authentication methods can't be applied on the same page).
Is there a way of getting IIS to pass through the windows domain account name of the requesting user? I don't need proper AD authentication, just the domain name.
