I've handled a problem, that my IIS server uses Local Machine certificates, but I want it to use Current User certificates. I can't import certificate because it's protected by private key.
How can I switch type of certificates, using by IIS?

I'm running a Windows 2012 R2 environment that hosts a website in IIS. The website currently requires a client certificate (which is validated) to access the website.
The client certificate is checked to ensure that it is valid and has not been revoked, not for identification by the operating system. If the user presents a valid certificate, the information on the certificate is used to authenticate and identify the user in the application code (the actual authentication is Forms Authentication). There is no mapping of the client certificate to an individual user (e.g. the client certificates does not map to an active directory account).
The site currently utilizes an additional piece of software to pass the client certificate to an external OCSP to verify the certificate status.
My goal is to remove that additional piece of software and be left with an IIS only (or Windows Server only) solution, but the documentation has me confused. I'm not sure if I need to install the OCSP role on the IIS server or our AD server, or if there is a way in IIS to configure a URL to check the certificate.
If the client certificate is pointing to an OCSP server in its extension, IIS will automatically validate it. You might check the CAPI2\Operational event log to see what happens during the validation.
I have Send Port with Dynamic Solicit-Response type.
Everything needed for the Send Port is dynamically configured inside the Orchestration and Security Mode is set to Transport.
Encryption Certificate for the Send Port is not configured. (I guess IIS already handling it?)
Decryption Certificates for Host and IsolatedHost instances are also not configured. (this is the part where i believe that BizTalk will trust certificates depending on current certificates in Trusted Root Certification Authorities)
Yes, the Send Port will make request on endpoint that uses self-signed certificate.
What I tried:
I tried importing the self-signed certificate in Trusted Root Certification Authorities, Other People under Local Machine and Current User (User that owns the BizTalk host)
I tried manually setting up the Encryption certificate to use the self-signed certificate
Nothing works...
If the security mode is Transport, then the certificate that is needs will be one which contains the public key and that matches the target server. If this is a self-signed certificate then it needs to be in the Trusted Root Certification Authorities, Certificates for the BizTalk Host User.
I have website hosted on IIS. My main issue is that I want only users with a specific certificate installed to be able to access the site. I tried to follow some tutorials but I can't find anyone covering both server and client side, since I can't get it to work.
I have some questions to the main issue:
What kind of certificate should I use (domain/selfed signed in IIS 7.5)? I do have access to a Active Directory Certificate Services where I can create other types of certificates (CA), but the problem is when trying to import them to my IIS ("certificate cannot be used as an ssl server certificate")
I would like to use a CA certificate, but is that possible when using IIS? Or do I need to write all the code the check if the user has the right certificate?
When created a certificate for the website (e.g. though IIS)..How do I create user certificates that are trusted by the server certificate?
As you may noticed by now I'm not sure how to do all of this, and would really like some help..
Server should use SSL server certificate. This certificate has to have Server Authentication extension in Extended key usage. Server certificate should have SAN extension (Subject alternative name) with domain name of server as DNS name (i.e. somesite.com)
CA certificate has to be imported to Trusted root store (preferably Local Machine) on both server and client machines.
Client certificate should contain Client Authentication extension in Extended key usage.
All EndEntity (client and server) certificates should have CRL distribution point in them where there is URL to CRL that is issued by CA. CRL has to be accessible by both client and server and should be always valid.
You can use XCA for training purposes. It has a nice GUI and it has templates for CA, SSL server and SSL client certificates by default. Then you can mimic these certificates in your Active Directory Certificate Services. Documentation and some guides can be found here.
I have a linux server with apache tomacat running on that . In my application I am using a two way SSL authentication and the server is generating a certificate for each and every client for mutual authentication using a root certificate and signing it with a private key.
But I am not aware how to install the private key and root certificate on my server. Is it possible using putty as there is no user interface enabled on server.
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

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!)
