In one of my applications, I enabled the configuration on IIS to accept the client certificate, by enabling like the below picture. The same configuration I did on the local IIS server and it works.
but it's not working. Any configuration that I am missing..?? At least it should prompt for the Certificate.
It will prompt the client to provide a certificate only when accessing https:
You need to check whether to access the service via https.
I think you need to install the cert in cert store in current user for the browser to show up the dialog box with list of certificates

We have an application deployed to IIS and every time we connect to it, we get the following browser prompt:
Select a certificate to authenticate yourself to sitename
We do not have a reason to challenge for a client certificate and seems like this setting was introduced by mistake
How can we remove it?
Research:
This question on How can I prevent browsers from prompting Users for a Client Certificate? looks similar, but doesn't have an answer yet, and also is about setting this up on kestrel-http-server
This question on Browser is not prompting for a client certificate is for how to make sure there is a prompt, and didn't provide enough hints as to how to prevent one
Open IIS and navigate to your web site or application and go to the SSL settings
Set the Client Certificate setting to "Ignore"
Both 'Accept' and 'Require' will both challenge for a client side cert
Recycle your app pool and re-launch your browser to test
Note: SSL settings are inherited from your Site > Application, so you may need to apply these SSL Settings at multiple levels

We are developing ASP.NET application and we need to use Client Certificate Authentication on IIS 8.
I followed guides to setup SSL and Client Certification authentication.
https://blogs.msdn.microsoft.com/asiatech/2014/02/12/how-to-configure-iis-client-certificate-mapping-authentication-for-iis7/
and
https://blogs.iis.net/rlucero/iis-7-walkthrough-one-to-one-client-certificate-mapping-configuration
I've setup client certificate and added one-to-one mapping to map it to local administator account (once it works, i will change it to more resticted user).
I validated that both server and client certificate are valid and trusted on server and on clinet. So there is no problem with certification authority.
When i try to acces the web page i am promted to choose client certificate. When i confirm selected certificate i allways get 401.1 result: Unauthorized.
I think that it can be related with that in IIS Authentication settings i disabled all authentication types. When i enable Windows Authentication, it seems to work - I am prompted to select certificate and when i confirm selected certificate, i am prompted for username and password and then page is displayed correctly. Of course i do not want user to enter windows user name and password.
PS: Error log file from IIS is here https://www.dropbox.com/s/pe8qwxpgilr347l/fr000156.xml?dl=0
Thank you for any tips.
In my case, i needed to install and activate "client certificate mapping authentication" in Windows Server Manager "Roles and Features" and the IIS configuration editor here: system.webServer/security/authentication/clientCertificateMappingAuthentication
I have installed SSL on node server. I have made changes in app.js too.
Now when i am trying to run my website
example.com
I am getting Popup like this
Why i am getting this popup?
Is certificates doesn't installed correctly?
Thanks
The browser is asking you if you wish to authenticate yourself to the server using a certificate.
Clearly you have a certificate and a public/private key pair attached to your local account, or it wouldn't be asking you.
Simply click cancel if this is not intended.
Use the Windows Certificate Manager to check what certificate it is. In all likelihood you have installed the server certificate as a personal certificate on your account.
In the Server
I have configured a intermediate certificate .pfx file in the IIS and created a https (443) port using binding option. I use certificate for Authorisation also I am expecting a client certificate from the client , I enabled the Require SSL and clien certificate required option in the IIS.
I checked the Intermediate certificate authorities for the root certificate and they also presents, checked the .pfx file installed in the certificate store (Local Machine) also presents.
I created .cer file from the above .pfx file with include private key option and shared the .cer file with my client and he has to attach the .cer file for authorisation .
Above is the REST wcf service with POST.
In the Client Side
I tested this application after getting the .cer file, attach that to my request in my client.exe and calling the service - it returns .403 fobidden error.
In the IIS log it is logged as 403.16 , sc-win32-status code = 2148204816 error
Please help me my above approach is correct and how to avoid this error.
Is configuring CTL is the option , or I need to get a separate client certificate for use from my client side.
You need to make small steps to debug this.
First import SSL server certificate to LocalMachine\My store. Verify
that certificate is trusted (by double-clicking it and verifying
chain).
Setup SSL binding in IIS. Verify that you can access the https site (even WCF service gives some documentation page on http/s).
Import client certificate in client CurrentUser\My store. Verify that certificate is trusted (by double-clicking it and verifying
chain).
Set SSL require mode on your WCF service on IIS. Verify that when you access https site of the WCF service a certificate is prompted and no trust error is returned (again, the documentation page should be displayed)
Server certificate must have Server Authentication extension. Client certificate must have Client Authentication extension in it. Client has to trust server certificate. Server has to trust Client certificate. This means that CRLs from both chains must be reachable.
I'm new to mutual SSL. Therefore my understanding how client certifcates might be wrong.
When using Client certificates in IIS, do they need to be issued from the same certificate (or CA) as the IIS HTTPS binding has configured?
My dev IIS has a self signed certificate.
For the client certificate, I've created a CA and a Client certificate according to
the post here.
The CA is in my "Trusted Root Certification Authorities" of the local Computer.
The Client certificate is in my personal certificate folder.
On IIS I've set Client certificates to accept.
The first strange Thing is that when I browse to my page, the IE always shows me 403.7. Even I've disabled the IE setting "Don't prompt for client certificate selection...", there is no window opening for the certificate selection.
Also when accessing the page with a HttpWebRequest with Client cert attached, the response is always 403. Unfortunately there I did not figure out how to get the sub status.
Why doesn't IIS accept my Client certificate when the RootCA of the Client certificate is in the trusted root store?
Is there a way to get more details where the problem might be?
Thanks
Thomas
Finally could solve the issue:
The CA and Client certificates which I generated according to the tutorial here did NOT have the private key assigned in the certificate store. I had to remove the certificates from the cert store and Import the PFX file including the private key.
Second, the client certificate needs to be in the Current User/Personal store so IE does pick it up. I initallly generated it in the Current Computer/Personal store.
There might be a direct way how to create the two certificates including Private key with makecert. But the PFX import was the easiest way for me.
After 3 days of try and error on my side: If you use IIS10 on Windows2022, TLS1.3 is turned on by default.
The SSL handshake seems not to be implemented correctly in browsers/curls/.... for this case.
For testing reasons turn off TLS1.3
In
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server
Add:
DisabledByDefault as Dword with 1 and restart the server (not only IIS!)
