I am trying to setup IIS Client Certificate Mapping Authentication and so far I have been unsuccessful.
I have a valid client authentication certificate
I disabled all authentication methods in the Authentication feature of IIS for the target website
Using the configuration editor I setup iisClientCertificateMappingAuthentication as documented in various sources. In this series of screen we map a domain account to a certificate. This is done by exporting the certificate to a text file, removing the first and last line and making sure all is in one line.
The problem is as follows:
When I try browsing to a test page, browser correctly prompts for selection of a certificate. I select the correct certificate. I then get presented with
HTTP Error 401.2 - Unauthorized
You are not authorized to view this page due to invalid authentication headers.
If I enable Anonymous Authentication then it works, but the user is not the one in the mapping it is the user running the browser. I know this because the test page contains the following:
response.write (request.servervariables("LOGON_USER"))
response.write (request.servervariables("AUTH_USER"))
So the questions are:
For IIS Client Certificate Mapping Authentication, is this the only authentication feature that needs to be enabled?
Do we need to use the Authorisation feature to limit the users to the one provided in the mapping?
What I am trying to achieve is that only clients that have the certificate will be able to access the service.
What am I missing?
Cheers

Am i out of luck or is there an option to specify that only a single path/endpoint should require client certificate ?
The scenario:
IdentityServer4 gives our users the option to sign in multiple ways (Username/Password, Azure AD or ClientCertificate)
The first two are working as intended, but the certificate paths does not prompt the user for his/her certificate, i know its possible with IIS but we want to run this using Kestrel.
If i setup the projects kestrel setting to require cert all endpoints requires it, this ruins the user experience when signing in with username/password og azure ad.
Are there any options for setting only out localhost/certificate path to require certificate and then in turn prompt the user to provide their cert when being redirected to that paths endpoints if there is no cert present in the request?
Resolved it by setting up two hosts, and capturing the request in the certificate challange endpoint and checking the connection, if there's no certificate present AND the connection is using the non-requirecert connection i redirected the context to the right connection and was then prompted to supply the cert and login works as intended.
I am working on a project that uses an MFC module with CDHtmlDialog dialog in order to display a log-in screen to the user. I pass an https url to Navigate(), and then handle OnDocumentComplete(). I want to be able to verify the SSL certificate of the server that corresponds to my https request.
I've searched the net for how to do it with CDHtmlDialog API but couldn't find an answer. There is always the option to code it differently using openSSL or WinHTTP (which support SSL) and not using CDHtmlDialog but I prefer to save the time of implementing the whole module from scratch.
Does any one know how to verify SSL certificate with CDHtmlDialog?
I was wondering if the twisted webserver offers the possibility to restrict access to some resources using client certificate based authentication and to allow access to other resources without certs.
I searched trough the questions and found this posting: Client side SSL certificate for a specific web page
Now my question is if someone knows if twisted has implemented the ssl renegotiation and how an example would look like.
Or has there been a different approach since then?
Just to make things clear and to give additional information:
What I actually want to achieve is something like this:
A new user visits a site and has not yet granted access to the resource because he has no token yet that allows him to view the site.
Therefore, he gets redirected to a login resource that is asking for a client certificate. If everything is correct, additional data retrieved from the certificate is stored in the session, which makes up the token.
He then gets redirected back to the entry site, the token is validated, and according to his authorization level specific content is displayed
If I understood you correct Jean-Paul, this seems to be possible to implement with your strategy, right?
Correct me if I'm missing something or doing it wrong.
It doesn't seem to me that SSL renegotiation is particularly applicable here. What you actually want to do is authorize a request based on the client certificate presented. The only reason SSL renegotiation might be required is if you want the client to be able to request multiple resources over a single persistent HTTPS connection, presenting a different client certificate for each. This strikes me as unlikely to be necessary (or at least, the reasons for wanting this - rather than just letting the client establish a new HTTPS connection, or just authorizing all your resources based on a single client certificate - are obscure).
Authorization in Twisted Web is straightforward. Many prefer a capability-like approach, where the server selects a resource object based on the credentials presented by the client. This resource object has complete control over its content and its children, so by selecting one appropriate for the credentials presented, you completely control what content is available to what clients.
You can read about twisted.web.guard in the http auth entry in the web in 60 seconds series.
This will familiarize you with the specifics of authentication and authorization in Twisted Web. It will not tell you how to authenticate or authorize based on an SSL client certificate, though.
To do that, you'll need to write something similar to HTTPAuthSessionWrapper - but which inspects the client SSL certificate instead of implementing HTTP authentication as HTTPAuthSessionWrapper does. This will involve implementing:
IResource to inspect the transport over which the request is received to extract the client certificate
implementing a credentials type which represents an X509 certificate
implementing a credentials checker which can authenticate your users based on their X509 certificate
and possibly implementing a realm which can authorize users (though you may have written this already, since it is orthogonal to the authentication step, and therefore is reusable even if you don't want to authenticate with SSL certificates)
This functionality would be quite welcome in Twisted itself, so I'm sure you can find more help from the Twisted development IRC channel (#twisted-dev on freenode), and I hope you'll contribute whatever you write back to Twisted!
I need to make something like ssl certificate authentication at website. As far as I understand my task I need to get user's ssl certificate and send it to server what will decide can user be authenticated or not.
How can I get user's SSL by javascript and send it to server? Is it possible at all? Or maybe my approach is wrong or I do not understand my task correctly.
Maybe my solution will be useful for somebody. At IIS server configuration we need to check require users certificates checkbox. Than user when opens site will be asked for a certificate form personal certificates storage.
After if public certificate can be accessed from a Request object (c#) at server. From it we can get user's details and allow or deny login
Does anybody has a WebLogic 8.1 two-way SSL full example?
I am developing a small web application (1 HTML, 1 Servlet, 1 JSP) to send confidential data. The client could be a web browser. The server is WebLogic 8.1.
The information should travel encrypted. Besides, the web application needs to authenticate the client, using more than a username/password combination. I thought implementing using HTTPS and two-way SSL authentication. This way, the user should send me her certificate, I installed in the server, so the web application could know when it is sending information.
Now, I know how to use declarative authorization in a web application, but I am lost on how specify which users I recognize, and which are their certificates.
I just need a full example of this. A .war and/or the steps to do the basic case.
I don't think you'll find a full example easily and the question is a bit broad. But the link your provided is a very good starting point.
First configure Two-Way SSL and use CLIENT-CERT. Clients will need to buy a trusted client certificate or to generate a self-signed certificate that you'll need to add to the server trust store. This may be the hardest part if you're not familiar with PKI but I've added resources at the end of this answer that cover this part. Load the client certificate in each client browsers.
Second, configure an Identity Assertion provider to map the digital certificate of a Web browser to a user in a WebLogic Server security realm. If required, provide your own user name mapper or use the default one (which uses the attributes from the subject DN of the digital certificate or the distinguished name to map to the appropriate user in the WebLogic Server security realm).
Third, add users corresponding to the Subject's Distinguished Name (SubjectDN) attribute in the client's digital certificate in Weblogic Security Realm and assign them to groups.
Finally, use these groups in your declarative authorizations.
Sure, it won't be that easy if everything is new but that's basically what you need to do. Maybe start to implement it and open more specific questions if you need more guidance.
