Subject SSLHostConfig configuration
Date Mon, 09 Sep 2019 22:28:52 GMT
All,

We have a Tomcat application (that ships/includes Tomcat with it) that
requires we use multiple domains and therefore set up SSLHostConfig
settings in our server.xml file to accommodate each domain.  We have been
using this configuration and it works well:

Tomcat 8.5.32

<Connector port="8443"
                maxHttpHeaderSize="8192"
                maxPostSize="6291456"
                maxThreads="200"
                protocol="org.apache.coyote.http11.Http11NioProtocol"
                executor="appExecutor"
                enableLookups="false"
                acceptCount="100"
                connectionTimeout="20000"
                disableUploadTimeout="true"
                URIEncoding="UTF-8"
                SSLEnabled="true"
                scheme="https"
                secure="true"
                defaultSSLHostConfigName="*.example.com">

                <SSLHostConfig hostName="*.example.com">

                        <Certificate certificateKeystoreType="PKCS12"
                        certificateKeystoreFile="/app/config/keystore.p12"
                        certificateKeyAlias="example_wildcard"
                        certificateKeystorePassword="maskedpasswd"
                        type="RSA"/>

                </SSLHostConfig>

                <SSLHostConfig hostName="*.example.ca">

                        <Certificate certificateKeystoreType="PKCS12"
                        certificateKeystoreFile="/app/config/keystore.p12"
                        certificateKeyAlias="example_ca_wildcard"
                        certificateKeystorePassword="maskedpasswd"
                        type="RSA"/>

                </SSLHostConfig>

<SSLHostConfig hostName="*.example1.com">

                        <Certificate certificateKeystoreType="PKCS12"
                        certificateKeystoreFile="/app/config/keystore.p12"
                        certificateKeyAlias="example1_wildcard"
                        certificateKeystorePassword="maskedpasswd"
                        type="RSA"/>

                </SSLHostConfig>

   </Connector>


This works fine in 8.5.32.  However, we are rolling out an updated version
of the application and it ships with Tomcat 8.5.40.  If we try to run with
the same configuration above in the 8.5.40 version of Tomcat, the
application fails to start with the following SEVERE error:

As you can see it complains about "trustAnchors parameter must be
non-empty".  However if I try to add trust entry lines into the connector
config:

<snip>
<Certificate certificateKeystoreType="PKCS12"
                        certificateKeystoreFile="/app/config/keystore.p12"
                        certificateKeyAlias="example_wildcard"
                        certificateKeystorePassword="maskedpasswd"
                        truststoreFile="/app/config/truststore.p12"
                        truststorePassword="maskedpasswd"
                        type="RSA"/>
<snip>

I still receive the same SEVERE error.

Questions:

1. What has changed in between Tomcat 8.5.32 --> 8.5.40 that seemingly now
requires truststore information in this connector configuration?

2. What needs to be done to allow this to work in the 8.5.40 Tomcat version?

Thanks in advance, any guidance is greatly appreciated.
