I need to enable Windows Authentication from my web.config, without setting it in IIS.
I have the following elements in the web.config:
authentication mode="Windows
identity impersonate="true
However windows authentication is not working. How do I resolve this problem ?
For IIS Express
You can set it up here. You may also wish to disable anonymous access
For IIS
I found it was necessary to set this under system.webServer
<system.webServer>
[…]
<security>
<authentication>
<anonymousAuthentication enabled="false"/>
<windowsAuthentication enabled="true"/>
</authentication>
</security>
</system.webServer>
This does almost the same thing as the #Dimitar suggestion - use IIS Manager to change the setting. The difference is that the config file avoids a manual step - but adds this next one:
Note:
By default, IIS Feature Delegation locks some of those settings (Basic & Windows auth), so you'll need to go to the root of the IIS server, and enable those to be read/write. E.g.:
A more detailed description of accessing Feature Delegation is here.
If by this you mean running your project from Visual Studio (IISExpress - not IIS), then you can try to do the following:
In Visual Studio -> Click on the root of your project -> Press F4 in order to open the properties pane -> Look for "Windows Authentication" and mark is as "Enabled" -> Run your project.
Unfortunately you must use IIS to enable Windows authentication. You cannot do it in Web.config alone. (At least up to IIS 8.5, the current version as of this post.)
This is because the Web.config elements for enabling Windows authentication (<system.webServer><security><authentication><windowsAuthentication>) can only be defined in applicationHost.config (C:\Windows\System32\inetsrv\config).
If windows authentication is not installed on IIS it won't work. If it is installed setting in web.config should be fine

I migrate an dotnet framework web api application from vs 2010 to 2019.
I want to use IIS express for developpement mode debug.
My application is built with a api back in dotnet framework 4.5 using xml and not json and a front in dotnet winform.
sorry for the french messages.
thanks a lot for your suggest.
I've been stuck with this for a week

I tried to change the web.config, the applicationhost.config (in the user iis express directory and the .VS\config directory.
add modules to IIS manager
Try removing this line from your web.config,
<identity impersonate="true"/>
Or,
as Described in here;
Your application's Web.config file specifies "identity
impersonate='true'".
In IIS 7 Integrated mode, client impersonation is not available in
some early request processing stages. Therefore, IIS will generate the
migration error message. If your ASP.NET Web application impersonates
client credentials (most common with intranet scenarios), you may want
to set the validateIntegratedModeConfiguration attribute to false.
Add this section to your config to overcome this issue,
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>
thanks for your help
I have tried
validateIntegratedModeConfiguration="false"
and it worked only when I deleted the lines created in the applicationhost.config (but it's not a solution)
we finally found: the problem was that I modified the .csproj file; but the file used for the user configuration is the .csproj.user.
It is modified with the "property" tab of VS.
I had seen it in a post for an mvc web application, since we are using an api, I thought it was different because it is an api.....
My colleague showed me the options in the panel... and now it works!!!!
[]You have to modify in properties :
anonymous authentication : disable
windows authentication : enable
pipiline mode : classic
and that's all
Make sure all the following .NET modules are installed.
.NET SDK 6.0.100
.NET Runtime 6.0.0
.NET hosting 6.0.0
note that the above are the current versions the versions may differ.
also change the version of .config files by running as Administrator whether you open the .json on Notepad or your IDE.
make sure your Internet Information Services is up to date and have selected all features on IIS
We have an application which is developed using MVC3 and .Net framework 4.0. To prevent HTTP Verb Tampering, we have included below code in application's web.config file. In local machine given fix was working as expected and returns 401 unauthorized code.
<authorization>
<allow verbs="GET" users="*" />
<allow verbs="POST" users="*" />
<deny verbs="*" />
</authorization>
When we deployed the same code, test result returns 202 OK. So the fix is not working. Is there any way around that we can fix this issue?
Are you are working with the "Play" button on Visual Studio? Is this using a IIS Express or are you really "deploying" that to an IIS WebAPP on your local machine?
I usually do not use the "Play" button when I am developing for IIS, specially when I am developing for a specif IIS Server. When that happens, I try to have the same IIS Server configuration on my machine and create a WebApp pointing to my Dev folder to test it.
If you are having trouble to config your web.config, I would use the IIS visual tools, check the modifications made on the web.config and commit that.
Please note that there are some differences in the configuration in the ASP.NET side and on the IIS side:
Please check this website:
https://learn.microsoft.com/en-us/iis/manage/configuring-security/understanding-iis-url-authorization
And refer to these notes:
Differences Between ASP.NET URL Authorization and IIS URL Authorization
There are small but important differences between ASP.NET UrlAuthorization and IIS URL Authorization.
ASP.NET Url Authorization is installed when you install ASP.NET on top of IIS.
This refers to IIS 7.0
Even though several configurations are compatible between one IIS to another, some specific changes might apply.
I was a user of visual studio 2012 but now i get switched to visual studio 2015.
Newly developed applications are working and running fine on development server but when I open old .Net applications and runs them it's generating error given below:
An ASP.NET setting has been detected that does not apply in Integrated
managed pipeline mode.
How can I resolve this ?
Can anyone help me please?
I just Added the following lines in web.config file under configuration TAG :
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>
Follow the answer in this SO thread
There are three options to solve this.
Change the Application Pool mode to one that has Classic pipeline enabled.
In web.config / web app will need to be altered to support Integrated pipelines. Normally this is as simple as removing parts of your web.config.
Add the following to your web.config.
I've created a WebApi with .Net.
On localhost (Visual Studio) all works well.
Also, when I publish it on a IIS 7 on a Windows Server 2008, it works well too.
Now I want to secure some methods.
I've created as
public class BasicAuthHttpModule : IHttpModule
and in the web.config I configured this as
<system.webServer>
<modules>
<add name="BasicAuthHttpModule" type="WebHostBasicAuth.Modules.BasicAuthHttpModule"/>
</modules>
</system.webServer>
The mehod I want to secure has [Authorize] above it.
On my localhost (debug in Visual Studio) it works well again.
With Postman I see that I can access the method with the specified username/password.
But when I put this on the IIS server, I get a 500 Internal Server Error:
500 – Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed
Must I configure IIS somewhere to achieve this, or has this an other cause?
Ensure that you have "Basic Authentication" installed for your IIS server.
Follow the steps as to how to manage which features are installed for IIS on your server by following the steps provided here: http://technet.microsoft.com/en-us/library/cc771209.aspx
Ensure that the feature "WWW-Service" -> "Security" -> "Basic Authentication" is selected.
Alternatively, ensure that the IIS user has the required rights to the folder/files of your site. Depending on what your site does, "Read and Execute" could be enough.
The user that is used for IIS7 is IIS_IUSRS.
Additional reading on the users of IIS can be found here: http://www.iis.net/learn/get-started/planning-for-security/understanding-built-in-user-and-group-accounts-in-iis
Already solved it!
I've discovered that there were two <modules> inside the <system.webServer> what caused the error
It works on localhost, but finds no default document on the webserver and complains about directory browsing being disabled. IIS7 on both, and both websites/app pools seem to be configured identically.
I've used the web api template in VS2012, which doesn't actually have any views. It only has an Index controller action in the HomeController.
Any ideas on why this could produce different behavior in the two environments?
So this addition to my web.config:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<system.webServer>
fixed the problem. It seems to be required in the web.config for IIS7 on Windows 2008 Server, but not for IIS7 on Windows 7.
I had a user trying to publish a MVC4 application on IIS7 getting this error, it turned out it was because the user had set the application pool to use .Net 2 instead of .Net 4. Instead of getting an error indicating this though they received the above error, and it was only when we added the above module the real issue was uncovered.
