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 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'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" />

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'm in the process of learning ASP.NET and am still fairly new to the programming world.
While learning about authentication/authorization, I edited my sample app's web config file to enable forms authentication, and authorization to deny all non-logged in users. I created a blank Login.aspx form as well, but when I try to execute the app, no pages appear. IE shows:
"Page can't be displayed"
even though I'm told it should redirect to my Login.aspx file automatically. Other browsers such as Opera show:
"This webpage has a redirect loop"
This is what I have so far:
<system.web>
...
<authentication mode="Forms" />
<authorization>
<deny users="?" />
</authorization>
...
</system.web>
I tried adding the <forms> tag in between <authentication /> with loginUrl as Login.aspx, but still same error. I've also added the <location> tags to allow access to the App_Themes and Images folders.
I'm currently using VS Express 2013 for Web with IIS Express integrated.
Any help would be appreciated!
If this helps anyone out there, I finally found the solution to be that, when implementing the <forms> tag, the loginUrl attribute should have a value of just the NAME of the login form, WITHOUT the .aspx extension. So it looks like this:
<system.web>
<authentication mode="Forms">
<forms loginUrl="~/Login" />
</authentication>
<authorization>
<deny users="?" />
</authorization>
</system.web>
Thanks to whoever that tried to help!
Enable Anonymous Authentication in the IIS and then try.
Run->ingetmgr->IIS Group->Authentication->RightClick on Anonymous Authenticaion and Enable.
I'm having a problem with Forms authentication in my website. At the moment when a user is not logged in they get redirected to a login page, which works fine. However, I want an unauthorised user to get redirected to a new page (welcome.aspx). Having changed the web.config I get the following HTTP Error 500.19 - Internal Server Error:
Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'redirect'
And here is the relevant part of my web.config:
<authentication mode="Forms">
<forms name=".CommunityServer" protection="All" timeout="60000" loginUrl="welcome.aspx" slidingExpiration="true" />
</authentication>
<location path="Default.aspx">
<system.web>
<authorization>
<deny users="?" />
</authorization>
</system.web>
</location>
If I set Visual Studio to use the Visual Studio Development Server instead of my Local IIS WebServer, it all works fine. Also if I rename welcome.aspx to login.aspx it works fine.
Any Help is appreciated.
Have you tried
<authentication mode="Forms">
<clear />
<forms name=".CommunityServer" protection="All" timeout="60000" loginUrl="welcome.aspx" slidingExpiration="true" />
</authentication>
I cannot seem to isolate my forums to set different permissions for them than the rest of the site.
Here is the setup for my site.
<location path=".">
<system.web>
<authentication mode="None" />
</system.web>
</location>
I need to isolate my forums. At the moment, for testing purposes, I have it setup so that all users are denied access.
<location path="~/public/public-forum.aspx">
<system.web>
<authentication mode="Forms">
<forms loginUrl="public/login.aspx" />
</authentication>
<authorization>
<deny users="*" />
</authorization>
</system.web>
</location>
What I'm finding is that I can still access the forum page. This suggests to me that this isn't setup correctly.
Does the path attribute have to be relative? Does it have to point to the URL that the page is accessed through or the rewritten path? ~/public/public-forum.aspx is a virtual path that is rewritten so neither the directly nor the file exists with those names. Why does this currently not work?
I hope that's enough detail for a solution.
edit2:
So the solution isn't only in the comments :
As far as i know you cannot specify an authenticationmode per location.
You could set the forms authentication mode throughout your site and only require logged in users in the secure parts.
edit:
mmmh strange , are you sure you only edited the ~ away?
They discuss your problem here but i can't imagine how changing the ~ would trigger it.
Could you perhaps post your entire web.config?
Also : are you using iis 6 and virtual directories?
The ~ sign is not needed , try this :
<location path="public/public-forum.aspx">
<system.web>
<authentication mode="Forms">
<forms loginUrl="public/login.aspx" />
</authentication>
<authorization>
<deny users="*" />
</authorization>
</system.web>
</location>
