Security :: Avoid Windows Login Userid And Password Window When Use Windows Authentication Mode For Website
Dec 30, 2010
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...
Just to describe the scenario. I have a website. This lives on a webserver. On that webserver is an SQL server. The website connects to this database using windows authentication. I have written a windows form application that connects to the SQL Server on the webserver. This application is being run from a location on out intranet. The Winform application use SQL authentication to connect to the database. The SQL Server didn't have mix mode authentication enabled. So I enabled it. The winform application could now connect to the SQL Server.
This is where it starts getting a little strange.
The Website that was already connecting find using integrated authentication starts failing with:
Login failed for user 'NT AUTHORITYNETWORK SERVICE'
When you are enabling mixed mode authentication, you are adding another authentication method, why would the original Windows authentication fail?
We have developed a website in asp.net using windows authentication and deployed it on the intranet (IIS v6.0). Most of the times, when users try to access this website they are taken straight to the website, but occasionally some users get a prompt to enter their windows username and password. I understand that this could be caused because of several reasons like:
Cached active directory password. Recently active directory password changed. Active directory account locked out. I want to fix this issue for good because it is annoying the users.
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 had a problem login management studio (Sql server 2005) using windows authentication because it doesn't show me any server name to connect and if I put my computer name and user name (my-PCpatel) login was failed.
So, I decided to uninstall it and install it again using mixed mode authentication. After installation I select sql server authentication instead of windows authentication and put login name as "sa" and password that I had put it during installation. But the connect button is dark gray(the way I can not select it or press it on) while the other button (cancel, help, option) can be selected or pressed.So, why am i not able select or click on connect button?
We have a link in our site that pin points to sharepoint documents and we are retreiving some documents files (*.doc). Our sharepoint uses IWA (integrated windows authentication) which is prompted if we're trying to access that documents, unfortunately we don't want to prompt that window to authenticate the user. We need is to create a username and password and authenticate it. how can we do that.
Note* we have 2 server one for our application and the other one is for sharepoint.
I am working on an application that uses windows authentication. Within this application, we give the user the ability to change their password. The user can change the password just fine. However, after they change their password, that is when things get weird. Sometimes they can navigate through the application just fine. Other times, they click on a link and are immediately prompted to supply credentials. Occasionly they can click on a link but upon a second click they are prompted to supply credentials. Does the browser keep a token to the original credentials and use this when they request the next page? If this is the case, why can i continue using the site sometimes? Can I change the password and then assign that token to the request?
I have an silverlight application configured with windows integrated security. I would like to emulate the "Sign in as different user" functionality I would like to give the user, the option to click a button and show the windows authentication login window, so that the user can enter the "User name" and "Password" again using another domain account. (btw i found this question on another site but with no answers, I need the same thing so i copy/pasted a bit)
I have an Intranet web site that uses Windows Authentication and when a users password expires the do not get a prompt letting them reset it. We also have OWA and if they go there to check mail, it sends them to a page which allows them to reset it there. How can I trap for expired passwords and allow them to change it like they can with OWA?
I have an application that uses Active Directory to validate users as well as populate a couple doopdown list, the application is connected to sql database on a seperate server. When I first published the application I got an error from Active Directory I eventually found out that I had to embed a username and password within the code for active directory to work. When i sorted out this problem I got one with my SQL and again used a username and password to allow connection to the database.
My new problem is when a user other than me logs in the windows popup windwo appairs requiring user name and password to login. The program is writen for windows authontetation but form where I check the person loged onto the computer and check username against active directory. After the person clicks the "OK" button a couple time they then have to click the close to exit the screen. the user can look at a page but if they try any kind of processing they are required to log in again and this time they are not verified. I would like to get rid of the popup box and let the validation gor though like it dose in my location.
I have developed an Interanet web application using the windows Active directory authentication if user find then it automaticaly authenticated working correctly now my user wants the capability of being able to login to the intranet site as another user by providing the username and Password . For example, Team lead needs to login on other team memeber System to pefrom some task on his behalf if he or she is not aviable in office .
I have created a standard MS Login Page. However when I try to login on the page only by providing the Username system authenitcate the user ( not validating the password of that user)
I have an intranet web application, where i have windows authentication = true in web.config. I hear from end users that the website is aksing for their login credentials and they don't like it. By the way i am getting theusername from HttpContext.Current.User.Identity.Name and Domain Name from Mid(UserNameID, 1, InStr(UserNameID, "") - 1).In IIS, anonymous access is unchecked and Integrated wnidows authentication is selected.
I am using FBA(Form Based Authen) and Windows Authentication for my web application. FBA is working fine with username and pwd. I want to use the same username, pwd for windows authentication without retering credentials in default login screen. How to avoid the default login screen with custom authentication..
I want to create a small intranet web site with a login page that will authenticate against groiups of users in Active Directory. So for example if someone in Group A logs in they can get to web page X and if someone from Group B logs on they can get to web page Y. Is it possible to do this with the login controls without writing code? I thought it would be a fairly standard thing to do.
I need to apply Windows Authentication for my website. But We dont want the user to be enter the User Name and Password in the Popup coming default.We need to provide the user with the input controls in the aspx page,then using the credentials will need to implement the Windows Authentication.Is it Possible to pass the windows authentication username and password from the aspx page , to enable the Windows Authentication
I have an intranet set up with IIS and it is working fine with windows integrated autehntication. However I have some permissions set and when certain users do not have access they get prompted for their login and I don't want this. I want it to go straight to the access denied page.
I read that "In integrated Windows authentication, the browser tries to use the current user's credentials from a domain logon, and if this attempt is unsuccessful, the user is prompted to enter a user name and password. "
So I understand this is supposed to happen but I was wondering if there was anyway to not have it prompt for a username and password if the first attemp is unsuccessful.
i have a problem with the users authentication on my site. I made <authentication mode="Windows"> in my web.config. The LoginView shows "mycomputermyusername" if i request the page. So far as well. Now i want to login with a different username. Users are stored in an Active Directory. My questions: wich setting i have to do, that user's account and password checked by Active Directory? how can i force the system to make a new login? Logout doesn't work, i always see my on account.
We are having an issue with the windows authentication and IIS restart for asp.net application Our environment is an intranet site (an asp.net application ) that uses windows authentication, uses integrated security application pool, physical path credentials are set for a service account, who is admin for sql server, IIS etc. web.config - Connection string has Integrated Security = true, authentication = Windows, and authorization - deny *, allow = security group. Anytime we start - stop service (or restart) (IIS); and hit the website thru some other machine IE, it fails to show the website (401.2), and any subsequent hit to the website doesn't go thru.
However when we start the service, and hit the website on server's (where website is deployed) browser first time then everything works fine for subsequent hits from anywhere as long as authenticated on corp net and member of security group configured in web.config. This behavior however goes away if we uncheck the configuration "Enable Kernel-mode Authentication" on the asp.net application. ( but then Firefox browser stops working with this configuration!!) Why such behavior? In the documentation it states its recommended to keep it enabled. What is recommended way of publishing a website with windows authentication enabled? Any side effects of "Enable Kernel-mode Authentication" being unchecked ( other than what we found for firefox not working) Environment : IIS 7.5 windows 2008 Server R2, VS2008, SQL Server 2008, ASP.NET 2.0
