[keycloak-user] Not being prompted for x509 User Certs on KeyCloak version 4.8.3.Final

[Nalyvayko, Peter]

We have successfully tested and deployed the CAC card & X509 auth without any issues. One suggestion is In the SSL debug output search for a list of CA authorities the KC server sends back to the client as a part of mutual SSL handshake. For the mutual SSL to kick in, the  client certificates registered on the client machine must be  signed by one of the CAs from that list.

For example, say your trusted store has a CA cert with the Subject: CN=cert_auth

Then you should be prompted to select a cert only if your client cert's issuer (the cert used to sign the client cert) matches the subject above. 

You may also try  troubleshooting using "openssl s_client" to avoid digging through thousands of lines of SSL debug output

I hope it makes sense and helps :)

Cheers

--Peter

Thanks, I enabled the debug option for ssl in ../keycloak/bin/standalone.conf
if [ "x$JAVA_OPTS" = "x" ]; then
   JAVA_OPTS="-Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true"
   JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true -Djavax.net.debug=ssl"

I am seeing no errors in the logs related to certificates. I do see the root CA I'm trying to use along with the intermediate.
I am using a client certificate, but I'm providing it via a card reader on my computer. So I'm presenting a token on a smart card per say and not a soft cert loaded on my system.
Would this make a difference? Should I be seeing any sort of error output in the logs if the certs were loaded wrong or any other JAVA related issue?
I can post the debug output, but it's quite line.
-
Note, we currently use a commercial based IdP which accepts our smart card with tokens on them, so I assumed Keycloak by default would see a certificate loaded locally or via the smart card reader.

One possible reason you are not getting prompted is that the intermediate or root certs in your trust store do not match the intermediate or root certs used to sign the client certificates registered on your client machine. To troubleshoot the SSL handshake you can use -Djavax.net.debug, see https://access.redhat.com/solutions/973783 for more info.

Subject: [keycloak-user] Not being prompted for x509 User Certs on KeyCloak     version 4.8.3.Final

 I've read through all the documentation I can find online both with the
official documents and everything else I could find and I believe I have
everything setup, with additional logging turned on, but I'm not getting
any type of prompt for a x509 certificate when logging in.

 Here is the excerpts from the standalone.xml file where ssl-realm was
added to the management security-realms and under the subsystem.

    <management>
        <security-realms>
         ......
            <security-realm name="ssl-realm">
                <server-identities>
                    <ssl>
                        <keystore path="keycloak.jks"
relative-to="jboss.server.config.dir" keystore-password="mypass"/>
                    </ssl>
                </server-identities>
                <authentication>
                    <truststore path="truststore.jks"
relative-to="jboss.server.config.dir" keystore-password="mypass"/>
                </authentication>
            </security-realm>
            ......

        <subsystem xmlns="urn:jboss:domain:undertow:7.0"
default-server="default-server" default-virtual-host="default-host"
default-servlet-container="default" default-security-domain="other">
            <buffer-cache name="default"/>
            <server name="default-server">
                <http-listener name="default1" socket-binding="http"
redirect-socket="https" enable-http2="true"/>
                <https-listener name="default" socket-binding="https"
security-realm="ssl-realm" verify-client="REQUESTED"/>
                <host name="default-host" alias="localhost">
                    <location name="/" handler="welcome-content"/>
                    <access-log worker="default"
directory="${jboss.server.log.dir}" prefix="access" suffix=".log"/>
                    <http-invoker security-realm="ApplicationRealm"/>
                </host>

 I've setup the Authentication Flows for the Browser to have x509/Validate
Username Form above the new Browser flow and it's required.
Everything is setup per the KeyCloak documentation to include the binding
settings.

The only thing I'm not sure about is if the keycloak.jks and truststore.jks
files are the issue.
I have enabled extra logging as best I know, but I'm not seeing anything in
the logs of any relevance when trying to authenticate into the Keycloak
Realm.

Can anyone assist? We are looking to most likely purchase this as a product
through RedHat SSO if it works well to get the support we need, but I've
been hung up on this for a few weeks and I know it shouldn't be this hard.

Thanks,
J
