I have created an asp.net web application and deployed it in IIS10. The design of the application is to require a client certificate for each user which will be provided by us. For testing purposes I created a self-signed certificate using the makecert.exe and followed the instructions at https://blog.jayway.com/2014/10/27/configure-iis-to-use-your-self-signed-certificates-with-your-application/. I added the certificate in the MMC Personal Certificates.
I also configured the iisClientCertificateMappingAuthentication in the IIS Configuration Editor using the one-to-one mapping approach. When I tested it on the browser, at first it asked for a digital certificate (which is correct), but when I clicked the certificate I added on the bindings it returns an error "Your client certificate is either not trusted or is invalid."
What should be the problem here since the installed client certificate is already added in the IIS one to one mapping configuration? Do I need additional configuration in the IIS?

One of my clients java/Cold Fusion application is trying to access my WCF web service endpoint using client certificate mutual authentication.
We moved our wcf service to windows 2008 R2/IIS 7 machine and generated new certificate using 3rd party CA. After the change, client is getting 403.13 error.
On investigation, I found that the Certificate Request does not include the new certificate in the distinguished names list.
How can I configure IIS to include the client certificate in the trusted certificate list?
You can't add trusted certificates, it's done on machine level. If you open MMC and add the certificate plugin you should be able to add it to the Trusted Root Certification Authorities on the server.
I'm trying to setup a development environment on my machine for an ASP.NET MVC project where client certificates are requested when trying to reach certain controllers.
I've enabled SSL on the project through project properties on VS Studio, I've also imported IISExpress self-signed certificate into trusted CAs in my browser and the client certificate into personal certificates in the browser.
Now, when I try to reach the controller where the certificate is requested, my browser opens a list to select the appropiate certificate, but the certificate matching the IISExpress one doesn't appears in the list, although it's on the certification store on the browser.
Any idea about what to do next?
I have a client site that when a button is clicked it calls a wcf web service. The client site is http, while the url for the web service is https and requires a certificate. I have a valid signed private key certificate I am using.
Everything works fine on my localhost; however, after deploying to a windows 2003 server running iis 6, I get the below error when the web service is called:
Could not establish trust relationship for the SSL/TLS secure channel
with authority "host's url"
I added the cert to the store, using same web.config that works locally. I have validated that the web service call finds and sets the valid X509Certificate.
Not sure what I am missing, and I don't want to override the servicepiont manager to return true every time.
Any ideas or things I might looks into?
Found the problem.
The root certificate which the host of the web service uses was not trusted by my server. (not sure why it was on my local machine and not my server). I found this out by opening the host's url in a web browser from the server to view their wsdl and got the security warning.
Remedy: went to the issuer's site downloaded their root cert and added to my trusted root certifcation authorities.
Bam, it works now.
If it is a private cert it must be added to both the client and the server as no client can validate its root key.
Linked to my question about client certificate authentication done the right way I was wondering whether I have to take the step to link a certificate to a user (active directory or local user) in order to have clientcertificate authentication to work as expected?
And is it necessary to disable all other authentication schemes (anonymous, windows) for clientcerticate authentication to happen?
See this question on the IIS forum:
This is what I would like to achieve:
A SSL-certificate for the URL itself (https://example.company.com). To my understanding this certificate does not have any connection whatsoever to client certificates.
Client certificates issued from my local CA and shared to trusted clients.
Some way of specifying which client certificates are allowed to connect to a specific IIS web site.
3 seems... complicated, to say the least. If I just set everything up and connect with a client certificate I have issued it works. The CA and the web server are on the same domain (if that matters), and I have added the root certificate from the CA to the trusted CAs on the web server. However, at this stage I have not told the web server which client certificates to accept, so my first guess was that it accepts all client certificates [chained to] any CA it trusts.
See also this question, which links to this site, which is dead.
It comes down to creating a "Certificate Trust List", or to mapping certificates to user accounts.
You can however implement a custom certificate validator in your service, how to do so is explained here.
I have Azure app containing 4 sites in a single web role (differentiated by host headers). I setup the sites to run over SSL. I issued 2 self signed certificates: 1 as CA installed into Trusted Root CAs store and 1 wildcard SSL certificate (issued using the first one).
The application runs, however I'm getting certificate error 'Mismatched address' in Azure Compute Emulator. I examined the mismatched certificate and found out it is not the one specified in service configuration. I went into IIS management console and checked the bindings - there was no cert set for my sites. So I setup the wildcard certificate manually in the site bindings. But in browser I still have mismatched certificate, still the one for 127.0.0.1 (comming with DevFabric). How can I make the IIS to return the correct certificate configured for the site?
(I have some services in the web sites consumed by Silverlight application and it does not work when there is forced manual confirmation of the certificate by user.)
Thanks!
Are you sure that you really access the service using https://127.0.0.1 and not using https://localhost?
