Security :: Mixed Mode Authentication Fails In Multiple IIS Websites
Jan 26, 2010
I created a mixed mode authentication mechanism based on a few of the articles that I have read on this topic. It's similar to something like this: [URL]
Basically, there are two web applications. One accepts the Windows Auth and one accepts Forms Auth. The Windows Auth then creates a forms auth ticket and passes control to the Forms auth application. This solution works fine when both applications are housed within the same IIS web site.
Now, order to control the security of this solution we set up multiple IIS web sites on the same machine. Web Site 1 serves external traffic (forms auth) and Web Site 2 serves internal traffic (windows auth).
So the design is that an internal user can hit the site using Windows auth via a internal name (myserver) while the external users use Forms Auth hitting [URL].
All that said, the solution works when the two applications are in the same site. Doesn't work when they are in different sites.
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?
I have a question about mixed mode authentication. I've been doing some research into this, but I haven't found the answer yet, so I figured I'd just ask:
I have an internal application that requires login. Right now it's using forms-based authentication. We'd like to make it so that, if you're internal and authenticated against Active Directory, you don't need to login to the application. However, if you're coming in from the outside (or don't have an AD account), it would then require them to login via the forms-based Login.aspx page.
From my research, it seems that the only way to do this is to enable forms based auth as the default membership provider, then on the back-end do a check at Page_Load to pull their login name, match it against the .NET membership and then authenticate them automatically - am I wrong on this?
The documents I've found all seem to point to the user having to login anyway, just the login being stored in AD - instead of having the user just login once to their machine in the morning and using that to verify them and their roles in subsequent applications.
I'm having a tough time implementing mixed-mode authentication (windows & forms based) for my application using IIS 7. Doing it in IIS6 is easy, but the process doesn't translate to 7/7.5 - and my research has led to me to conflicting answers, none of which.
I have redirect page called WindowsLogin.aspx, and a forms-based one called Login.aspx. I'm having difficulty enabling Windows authentication for just WindowsLogin.aspx.
I am trying to implement single sign on for users within our domain and if the are not then they get re-directed to the login screen to use forms authentication.
I have followed this tutorial below
however I get two issues firstly if I go to my forms authentication page no css or images now display and if i try to login i get an error.
If I go to the login page which should recognise me from the AD I get 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.
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?
my user will use form authentication against Active Directory or database. Theres no Windows Integrated Authentication there!!
What i want is when the user submit the authentication form, it will try to validate the user against Active Directory and if it fail, try with the database.
How can i do that? What i had in mind was to build a custom membership provider that will encapsulate the logic but im not sure how to start.
I have a web application where users can authenticate using either SiteMinder or Windows domain accounts. This is actually configured as two separate virtual directories within IIS 6. Both applications need to use the same instance of SSRS. Is it possible to configure the SSRS web application so that if a user is authenticated by SiteMinder it impersonates a Windows account, but if they are already Windows-authenticated that account is used instead?
I have 2 web sites both located physically on the same web server, I'll call them siteA and siteB. These sites are accessed by internal users on our intranet as well as external users on the internet.
SiteA is is setup on IIS6 using basic authentication which we connect to an active directory. The web config is set to use Windows authentication mode. The url to site a is etoolbox.xxx.yyy
SiteB is the same setup. The url to siteB is rdow.xxx.yyy
What I want is once the user is authenticated against the active directory when the login to SITEA for them to be able to click the url in siteA which opens SiteB in a separate browser window and automatically takes them to the welcome page without being prompted for credentials again.
Currently when clicking on the url to go to siteB I am being prompted again for my credentials.
Is there any way for both external and internal users to only be prompted once for their active directory credentials and then be able to go to whatever site they want to without be prompted for credentials again? Is this something I have to code for or is it handled automatically by IIS?
we would like to redirect the user to a given page if the authentication to our SharePoint site fails (i.e. the standard windows login prompt pops up three times - we are using windows authentication). No matter what option we try it always ends up bringing the user back to a blank page.
We have tried writing a HttpModule (and catch the if Response.StatusCode = 401), which doesn't seem to fire any events if the user is not authenticated. We have tried writing a HttpHandler, but of course we can redirect the user if there is an error code but can't continue onto the desired site if not. We have tried doing the following in the web.config:
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.
I am in the process of designing application in case user authentication if failed i need to redirect to default page (NT Authentication). Is there any way you can redirect the user on IIS if the user is fail go through the NT authenticaiton at IIS level.Options 1 : Always land the user to defalut page and validate there and redirect to site based on the access give the directory level access. I am looking if there any options to let the user to default page in case user access is denied.
While running an app from the server where it is deployed the website works fine, however when trying to access it from a different machine(placed in same network), using the same credentials, it shows that I am not an authenticated user.
I am trying to implement a simple role based authorization using forms authentication in ASP.net. It works perfectly fine in my local system but fails when I deploy in production (shared hosting). Whenever I try to log in, rather than taking me to the default page in specified directory it throws me back to the login page. I suspect that there is some issues with the configuration but not sure where the problem is. The code is provided below:
Web.config (root):
[Code]....
Web.config (Member directory):
[Code]....
Login.aspx:
[Code]....
Global.asax:
[Code]....
Works fine in local machine but shared hosting is not taking the authenticated user to the pages inside the secured folders. What can be the issue?
I have an ASP.net website running with the authentication mode on the web.config file is Windows. The webpages at the root do not need to have login & password form.
Now I created a subfolder called 'reports' and would like to implement a few web pages with the login & password authentication form.
Question, do I need to create another web.config file in the 'reports' folder and update the authentication mode="Forms"?
This is annoying more than anything, but I have no working Intellisense when I use any of my custom web controls in .aspx/.ascx pages. Intellisense in standard <asp:...> controls are fine, as it is in all code-behind files etc.
I'm pretty sure this is caused by Visual Studio attempting to analyse the website's bin folder for custom web controls, and throwing a hissy fit when it gets to one of the DLLs - a (mixed-mode) 64-bit managed C++ assembly (I'm running 64-bit Win 7). It seems that Visual Studio tries to load this assembly, and fails, due to VS being a 32-bit app.
I looked for an option to get VS to ignore the 64-bit assembly (there are no web controls in it - they exist in another standard assembly), but alas, nothing to be found.
I have a problem in my asp application. In my application I have an own authentication mechanism so in the web.config file I have <authentication mode="None"/>
Inside the application users can upload files to the folder I've created (App_Files). I would like to give access to the folder only once they are logged in (Session["Login"] is no null).
I dont want not logged in users to be able to access the files over a url address in the browser (like http://<server>/App_Files/Filename.pdf)
I have the requirement for internal users to acces our web app without loggin in manually so using windows authentication, external users need to be refered to a form based authentication.
Now I have implemented the solution [URL] ....
However I also need to employ roles for authorization. The forms side is all set up but I cannot seem to get it to work for the windows side of things, looking for implementing a mixed mode involving roles?
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]...
I wanted my local iis running application to connect my database in sql authentication mode rather than windows mode,
but it is showing errors of " Cannot open database "aspnetdb" requested by the login. The login failed. Login failed for user 'DBUser'. ". i also ublocked port from firewall,and allowed remote connection of mssql from sql manager, enabled TCP/IP and named piped protocols from SQL surface config, and with sql manager i also changed server authentication mode to sql from windows. my datastring is <add connectionString="Data Source=PARTHIV-PCSQLEXPRESS;Initial Catalog=aspnetdb;User ID=******;Password=******/" name="LocalSqlServer" providerName="System.Data.SqlClient" />
i made a user named DBUser in database as well i don't understand where it gone wrong ???
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 have two applications with a single domain name ([URL] and [URL]). First one has been developed in .NET 2 and the other one with .NET 4. I have configured web.config as these steps:
1- I've set the same machine key for both of them. 2- I've set the coockie name. 3- I've set the domain name to "domain.com". 4- Also, I've set hardcoded coockie domain name to "domain.com" .
Everything was working fine when both of them were running on a single web server. Recently, I've been asked to move test.domain.com to another server. After moving, authentication ticket is not valid on the second server. I tested both of them on a single server again and everything was workinh fine, but in two servers users can't acces to test.domain.com. (Authentication Ticket is invalid)
Edited: The second server is a virtual (VMWare) server. I don't have any problem in physical servers. I checked the server's time to be synchronized. I also used fiddler to see if the server does not get the auth ticket and ther ticket is sent to the 2nd server. Note: Servers are located in different networks and maybe proxy or firewall causes this (I've no idea)
,Second and Third applications are accessed throught the first,So Authentication (form authentication) is happening from the first application only , all are deployed on same IIS with seperate virtual directory
Like
1.Localhost/EmpMananger
1. Localhost/Hr
2.Localhost/Payroll
, I used the same Entires in both <machineKey> and <forms> Elements in webconfig file of all applications,
Applications are working fine and Page.User.Identity are available in all applications but once loginUrl and defaultUrl entry is changed to actual name other than localhost
Eg: localhost/EmpManager/default.aspx To myserver/EmpManger/default.aspx
the authentication ticket is not available in second and third applicaiton
