I have a solution in MVC5. That is using windows authentication, the web config has the following settings:
<authentication mode="Windows" />
<authorization>
<allow users="?" />
</authorization>
I want to skip this windows authentication. That is setting a default username and password. For example
<username="Test" password="Password">
So that solution uses this user instead of windows user.
I want this because of some reason I have to develop the solution as a different windows user, that is not in an admin group. So some pages cannot be viewed by this user.
I have removed the authentication tag from web.config, But it's still not logging in when I enter the admin username and password.
You can just disable authentication:
<windowsAuthentication enabled="false" />
Possible to impersonate:
<system.web>
...
<authentication mode="Windows"/>
<identity impersonate="true" userName="<domain>\<UserName>" password="<password>"/>
...
</system.web>

I saw similar questions like this on here but I simply can't find a good solution.
My problem:
I have an app that need to retrieve data from a connection string, and information that is retrieved depends on the authenticated windows user. When I run this in dev environment with IIS Express I get my logged in user.
However when I host it via IIS Local i get ( IIS APPPOOL\ ) as the user. I need this to be the windows user.
Even tho I get the login the application still outputs APPPOOL when I check this in my views
Anyone with a good solution to this?
I tried:
#System.Web.HttpContext.Current.User.Identity.Name
#System.Security.Principal.WindowsIdentity.GetCurrent().Name
#HttpContext.Current.Request.LogonUserIdentity.Name
<system.web>
<authentication mode="Windows" />
<authorization>
<allow users="*" />
<deny users="?" />
</authorization>
<identity impersonate="true" />
<trace enabled="true" />
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>
It sounds like your application are always imepersonate as application pool identity.
I can get the correct windows identity via
System.Web.HttpContext.Current.User.Identity.Name
HttpContext.Current.Request.LogonUserIdentity.Name
User.Identity.Name;
First of all, please ensure your authentication looks like this. Please disable impersonate and anonymous at the same time.
<location path="mysite">
<system.webServer>
<security>
<authentication>
<windowsAuthentication enabled="true" />
<anonymousAuthentication enabled="false" />
</authentication>
</security>
</system.webServer>
</location>
Secondly,please promise your windows authentication are not executed with app pool credential
Finally, you should get the correct credential.
In Asp.net Application for windows authentication
In aspx page
asp:Label runat="server" ID="windows"
aspx.cs page
windows.Text = User.Identity.Name;
webconfig:
authentication mode="Windows"
but authentication is not performed what problem ??
Add the following in your web.config under system.web to make sure that the windows authorization is triggered:
<authorization>
<allow users="?" />
</authorization>
Your web.config wants to contain like this:
<configuration>
<system.web>
<authentication mode="Windows" />
<anonymousIdentification enabled="false" />
<authorization>
<deny users="?" />
</authorization>
</system.web>
</configuration>
This will force all users to use their windows/Active Directory login. A 401 Access Denied error will be given to those who don't log in.
Because Integrated Windows Authentication uses the current Windows
user information on the client computer for the authentication, it
does not immediately prompt the user for a user name and password.
However, if the authentication exchange cannot identify the user, a
dialog box appears that prompts the user for a Windows user account
user name and password
Source: How to implement Windows authentication and authorization in ASP.NET
Try adding the following block to see if it's working
<authorization>
<deny users="*" />
</authorization>
After adding this, run the application and you should get HTTP 401 - Access is denied error.
You can customize authorization from then on.
UPDATE:
Here's a different approach and how to configure it via IIS management console:
Deploy your site to IIS
Click on your site and select Authentication
Disable Anonymous Authentication and enable Windows Authentication as shown in the image below
Go back to features and select .NET Authorization Rules. Here you can add allow/deny rules on a role or user basis.
To test your current code deny anonymous users and allow all. When you connect to your application you should be able to use the Windows user you used to log in.
I'm making a simple website to learn about asp.net/AD authentication.
I used some of the code snippets from this tutorial: https://support.microsoft.com/en-us/kb/316748 to successfully use AD with Forms Authentication from a login page. I use these IIS Authentication settings for the website:
Anonymous Authentication -Enabled
ASP.NET Impersonation -Disabled
Basic Authentication -Disabled
Digest Authentication -Disabled
Forms Authentication -Enabled
Windows Authentication -Disabled
I want to use the credentials for the currently logged in windows user and either not prompt or only prompt if it fails. When I change the Web.config authentication mode to "Windows" and the the IIS settings as shown below it has a pop-up credentials prompt but just keeps prompting and never accepts the credentials.
Anonymous Authentication -Enabled
ASP.NET Impersonation -Disabled
Basic Authentication -Disabled
Digest Authentication -Disabled
Forms Authentication -Disabled
Windows Authentication -Enabled
I've tried several other combinations but they all failed.
All files in this website are:
LdapAuthentication.cs - is in App_Code and is a direct copy/paste from the tutorial
Logon.aspx - is copy/pasted from the tutorial with the companies LDAP path added
Default.aspx - is a direct copy/paste from the WebForm1.aspx in the tutorial
Web.config (shown below)
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.5">
<assemblies>
<add assembly="System.DirectoryServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
</assemblies>
</compilation>
<httpRuntime targetFramework="4.5" />
<authentication mode="Forms"> <!-- I also tried "Windows" -->
<forms loginUrl="logon.aspx" name="adAuthCookie" timeout="10" path="/" />
</authentication>
<authorization>
<deny users="?" />
<allow users="*" />
</authorization>
<identity impersonate="true" />
<anonymousIdentification enabled="false" />
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>
</configuration>
Ensure that IIS is right configured to use ActiveDirectory Authentication with Forms, it works with local server from Visual studio but not in IIS.
In IIS 7+ it's the application pool account.
- Simply create a new application pool that runs under that account and assign that app pool to your application/site.
- Right click to the new pool (example ASP.NET V4.0 Mypool) - > Advanced Settings
- In Process model, choose LocalSystem as Identity.
Web.config:
<system.web>
<compilation targetFramework="4.0" debug="true"/>
..........
<authentication mode="Forms">
<forms loginUrl="login.aspx" name="adAuthCookie" timeout="10" path="/"/>
</authentication>
<identity impersonate="false"/>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
</system.web>
I have a OData web api on visual studio using the ADO.NET Framework. I am getting an authentication window on chrome, I removed the authorize parts from the controllers and web.config file, yet the window asking username and password is coming.
How to remove it ?
My web.config file has
<system.web>
<authentication mode="Windows">
<forms requireSSL="true" />
</authentication>
<authorization>
<allow roles="myService" />
<deny users="*" />
</authorization>
which I removed but still authentication window is opening. Thanks a lot for your help.
Use None as mode for authentication-Element. The default value when you do not specify anything is Windows. More information about ASP.NET Authentication can be found here
<authentication mode="None">
<!--<forms requireSSL="true" />-->
</authentication>
I have developed an application to allow windows authentication and hosted it to the live server. in my local pc i am able to get the username password. but when i am accessing from web (e.g. websso.mydomain.com) it keeps asking credentials even after i entered correct credentials.
<authentication mode="Windows">
</authentication>
<authorization>
<deny users="?" />
</authorization>
<identity impersonate="true"/>
i have added above tags in web.config, hosting server is windows server 2008 R2. I have tried to get username from
WindowsIdentity.GetCurrent().Name
Environment.Username
Request.ServerVariables["LOGON_USER"]
Request.ServerVariables["AUTH_USER"]
HttpContext.Current.Request.LogonUserIdentity.Name
Is there any changes which needs to do in IIS or any steps to follow to configure windows authentication.
Installed IIS version is 7.5
I had a similar issue recently, try ensuring that the windows user has read access to the directory on the server.
Checkk application pool owner in IIS
It should be network services
websso.mydomain.com looks like internet domain name, not intranet domain name because it has sections. According to https://support.microsoft.com/en-us/help/258063/internet-explorer-may-prompt-you-for-a-password you should use domain name without sections (e.g. http://websso/) or add your domain name to security settings of client browsers
Try updating your <authorization> to include an <allow> element as I have done here.
E.g.
<system.web>
<authentication mode="Windows" />
<authorization>
<allow users="yourdomain\someotheruser" />
<deny users="?" />
</authorization>
