Security :: Authentication Using IIS's Windows Identity?
Jul 30, 2010
I want to know if this kind of authentication is possible.
We have an Active Directory account and that account we are using to log in to windows. I have a simple system that needs authentication using the IIS log in box (i dont know what do you call this but what I know is it only comes out when Anonymous user is unchecked in the IIS configuration.) Now, I want this box to appear before my page and the user will be authenticated and be compare to the user who logged in to the windows. If the user who have been authenticated is the same as the user who logged in to the windwos then we will let him in if not he must be denied in accessing the page.
The first problem I have in my mind is how to code it in asp.net to make an authentication when he will try to access my page.
Second is, let us say we have succeeded to show the authentication box, how can I get the username from the log in box and compare it to the user who logged on in windows. Of course we can get the user id of the logged in user from the windows using User.Identity.Name but how about the username from the log in box.
Note: I will not use log in forms even using https. Just the log in provided by the IIS according to the configuration.
In IIS 7.5 server I have a website apps.mydomain.com. Site binding for this website is:
IP: All Unassigned
Port: 80
Host name: apps.mydomain.com
In DNS there is an ip address pointing to apps.mydomain.com. Site comes up fine when browsing to this hostname.
I want to get current windows logged in username from asp.net web apps. I enabled windows authentication and disabled anonymous. Using this ASP.Net code to test:
Response.Write(Page.User.Identity.Name);
However, browsing to http://apps.mydomain.com/site/ the application pool identity shows as the Page.User.Identity.Name value and not the current windows logged in username.
If I browse to http://servername/site/ then Page.User.Identity.Name will return current windows logged in username.
Is there something else I need to configure to get the current windows logged in username when using host header?
My website security is configured with "Windows Integrated Security" only (anonymous is disabled).
I also want to set a specific account to run the w3wp.exe process using the Application Pool Identity to a domain account.
Running directly from the server works without any problem but from remote computers I always get the authenticaion window then the 401.1 error (after 3 attempts).
It seems that its the combination of "Windows Integrated Security" along with the "Application Pool Identity" that causes the problem. When I disable one of the two it works properly.
My server is Windows Server 2003 R2, running IIS 6.0.
I have an requirement to implement single sign on solution using SAML 2. I had a look at a tirdparty toolkit in componentspace, but I would prefer some microsoft components.
the features provided in componentspace toolkit can be done using some Microsoft .NET libraries itself. identify the microsoft way to do this?. I looked at the Windows Identity Foundation SDK, but it is now supported only for .NET 3.5. My web application is built on .NET 2.0.
Is there any alternative for Windows Identity Foundation in .NET framework 2.0?
I'm writing an ASP.net application that uses Windows Identity Foundation. My ASP.net application uses claims-based authentication with passive redirection to a security token service. This means that when a user accesses the application, they are automatically redirected to the Security Token Service where they receive a security token which identifies them to the application.
In ASP.net, security tokens are stored as cookies.
I want to have something the user can click on in my application that will delete the cookie and redirect them to the Security Token Service to get a new token. In short, make it easy to log out and log in as another user. I try to delete the token-containing cookie in code, but it persists somehow.
How do I remove the token so that the user can log in again and get a new token?
I have a webpage stored on a local server (Site A) which when I browse to it is given my windows account details, this site then checks within AD to get my email address. My email address is then passed to another website (Site B) and consumed. The Website A is set in IIS to Integrated Windows Auth Only, WebSite A has
<identity impersonate="false"/>
set in the web.config What I dont understand is what user is accessing AD from site A - with impersonate = false that is telling the site not impersonate the windows user, but this seems at odds with the setting in IIS.
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 currently have a client with a SharePoint site that wants to incorporate an (already written) ASP.NET application within a webpart in the SharePoint site. The ASP.net application currently uses an IIS impersonation account to connect to the SQL database.
Some added functionality the client is requesting would require me to grab the user's windows login identity to use the SharePoint UserProfileWebService to query the PropertyPages for that specific user. Because the (already written) ASP.NET application uses impersonation, when I grab the WindowsIdentity.GetCurrent().Name, I get the impersonation account and not the actual user's account.
Is there a way to keep the current setup (impersonation account on IIS to connect to SQL) and still grab the logged in user's credentials? Or would a better way about this be to change IIS to consume the Windows Identity of the logged in user and encrypt the connection string in the web.config?
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
And a SQL Server database with ASP.NET Membership and Roles. I am using the LoginView control with the AnonymousTemplate and LoggedInTemplate to manage the user's interaction with logging in and out. The problem I am having is that I am authenticating the user against the database:
If Membership.ValidateUser(_userName, _txtLoginPass.Text) Then returns True and: FormsAuthentication.SetAuthCookie(_userName, False) sets the cookie correctly: FormsAuthentication.Decrypt(FormsAuthentication.GetAuthCookie(_userName, False).Values(0)) {System.Web.Security.FormsAuthenticationTicket} CookiePath: "/" Expiration: #1/21/2010 1:42:27 PM# Expired: False IsPersistent: False IssueDate: #1/21/2010 1:22:27 PM# Name: "jaymo " UserData: "" Version: 2 but when I check HttpContext.Current.User.Identity.IsAuthenticated it always returns False. If done this before and it worked fine. I cannot find any mistake I might have made or where something might have changed between ASP.NET 2.0 and 3.5.
I've been trying to set a STS project in my solution following these steps on Channel 9. Right after hitting "Finish", I get an exception saying: The system cannot find the file specified. (Exception from HRESULT: 0x80070002). After installing, uninstalling, rebooting, and so on, I still get the error.
My OS is Windows 7 Enterprise x64, both Visual Studio 2010 and Visual Web Developer 2010 Express are installed in my machine, the WIF SDK 4, the runtime 6.1 and the Identity Training Kit from January 2011.
I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.
We use Sharepoint to control our websites. We build the sites, then load them into the sharepoint server. My question is if I use windows authentication, how can I get my role security in my web config file to coencide with the asp.net controls that use the Forms authentication. Is there a differenence? Our security uses a session variable for security but there is no where to set up their permissions except in active directory. I hope this makes sense because I would like to implement the LoginView with Role groups but how can I give them the role="administrator"? Do I have to go into active directory and give them these permissions(would take awhile due to the size of the company)? Or do I have to set up priveladges in the web.config file for each user(difficult I think)?
I'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?
I am trying to get the windows authentication for intranet design Codes return userid of my system but when I try the same fron other system, there too they return only my system's Id.
What I want to do is, if userA access the website, then the website will use userA's token to access the SQL server. Site is an intranet site.In web.config,I have
IIS:Annoymous login is disabled, Windows authenication is enabled.
SQL server:userA is added as a user to the database.
IIS and SQL server are on different server. Running as userA on another computer, I try to access the website. The website log told me the website was trying to login to the SQL server with NT AuthorityAnnoymous despite I specified to use integrated security and Annoymous login is disabled in IIS.
I have an application that ran fine on a Win 2003 box using windows authentication. After installing the app on a 32-bit Windows Server 2008 box the users are now prompted for domain credentials every time they call the site. I went into IIS manager for IIS7 and disabled anonymous authentication and enabled windows authentication. What do I need to do here for the user to not be prompted for the credentials?
I am developing one portal in asp.net. Im using windows authentication. In our domain, we are give 6 digit number as username. Based on the 6 digit number windows will display the user name. Can I got the user name from asp.net? Im using asp.net with C#.
When I trying with,
WindowsIdentity.GetCurrent().Name - it will return "DomainName123456". Instead of this 6digit number I need the user name. The user name is displaying in start menu.
What's happening is when windows authentication/authorization fails the user get's a login prompt in IE6, IE7 and FireFox. Only when user clicks Cancel button in login prompt they are getting to 401 error page. What I am trying to achieve is to automatically redirect the user to a custom error page when getting 401 error instead of getting login prompt. Is this possible to suppress the login prompt in this scenario or is it this way by design?Here is my setup:I have windows integrated authentication configured in asp.net 2.0 web app.
[Code]....
In IIS I have website Directory Security configured to use Integrated Windows Authentication and disabled Anonymous Authentication
We also have sales rep that take call and use the same website to take the orders.
My boss wants me to allow the SR to only be able to take orders if they are in the network itself. When I ask why he tells me "just because".
I'm sure there's a way but I can't see it at the moment. How do I go by doing that? Also keep in mind that if the SR is outside the intranet, he can't be allowed to enter his active directory login/password (so the login window must not even show).
