Bug ID: 62975
Summary: TLS 1.3: cannot perform post-handshake authentication
Product: Apache httpd-2
Version: 2.4.37
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_ssl
Assignee: ***@httpd.apache.org
Reporter: ***@integralblue.com
Target Milestone: ---

When using OpenSSL 1.1.1 with Apache 2.4.37, client authentication files with
these messages logged:

[Tue Nov 20 13:20:57.718509 2018] [ssl:error] [pid 8117] [client x.x.x.x:35692]
AH: verify client post handshake
[Tue Nov 20 13:20:57.718565 2018] [ssl:error] [pid 8117] [client x.x.x.x:35692]
AH10158: cannot perform post-handshake authentication
[Tue Nov 20 13:20:57.718591 2018] [ssl:error] [pid 8117] SSL Library Error:
error:14268117:SSL routines:SSL_verify_client_post_handshake:extension not
received

This problem does not occur if:
* OpenSSL 1.0.x is used
* If TLS 1.3 is explicitly disabled using the "SSLProtocol TLSv1.2" directive
* If "SSLVerifyClient require" is moved out of a Location/Directory block and
is directly in a VirtualHost section

Here's the vhost configuration I'm using:
SSLCACertificateFile /etc/ssl/DoD_CAs.pem
SSLOCSPEnable on
<Directory /var/www/localhost/htdocs/cac>
SSLOptions +StrictRequire
SSLRequireSSL
SSLVerifyClient require
SSLVerifyDepth 10
SSLOptions +FakeBasicAuth
</Directory>

The browser used is Firefox 63.0.3.

Not sure how what I said in the Fedora bug was unclear -- this is a bug in
Firefox, it needs to support TLSv1.3 Post-Handshake Authentication. There
isn't a mod_ssl problem here, mod_ssl is reporting that Firefox doesn't support
PHA.

The same problem is also visible with Chrome in Android and Linux Environment.
