Bug ID: 65415
Summary: ERR_BAD_SSL_CLIENT_AUTH_CERT by client certificate
Product: Apache httpd-2
Version: 2.4.41
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_ssl
Assignee: bugs@httpd.apache.org
Reporter: ppjjv...@gmail.com
Target Milestone: ---
CA certficate - OK
Server certificate: OK
Client certificate: OK
server and client signed by the same CA private key.
Environment.
OpenSSL 1.1.1f 31 Mar 2020
Ubuntu 20.04
Server version: Apache/2.4.41 (Ubuntu)
Server built: 2021-06-17T18:27:53
My problem:
connecting to a secure server requiring client certificate, i get the following
error when presenting my certificate:
ERR_BAD_SSL_CLIENT_AUTH_CERT
It started to fail after the previous one voided and i issued a new one.
CA, the same, server cert, renewed after previous voided.

# Server Certificate Chain:
# Point SSLCertificateChainFile at a file containing the
# concatenation of PEM encoded CA certificates which form the
# certificate chain for the server certificate. Alternatively
# the referenced file can be the same as SSLCertificateFile
# when the CA certificates are directly appended to the
server
# certificate for convinience.
#SSLCertificateChainFile /etc/apache2/ssl.crt/server-ca.crt
# Certificate Authority (CA):
# Set the CA certificate verification path where to find CA
# certificates for client authentication or alternatively one
# huge file containing all of them (file must be PEM encoded)
# Note: Inside SSLCACertificatePath you need hash symlinks
# to point to the certificate files. Use the
provided
# Makefile to update the hash symlinks after
changes.
#SSLCACertificatePath /etc/ssl/certs/
#SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt
# Certificate Revocation Lists (CRL):
# Set the CA revocation path where to find CA CRLs for client
# authentication or alternatively one huge file containing
all
# of them (file must be PEM encoded)
# Note: Inside SSLCARevocationPath you need hash symlinks
# to point to the certificate files. Use the
provided
# Makefile to update the hash symlinks after
changes.
#SSLCARevocationPath /etc/apache2/ssl.crl/
#SSLCARevocationFile /etc/apache2/ssl.crl/ca-bundle.crl
# Client Authentication (Type):
# Client certificate verification type and depth. Types are
# none, optional, require and optional_no_ca. Depth is a
# number which specifies how deeply to verify the certificate
# issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth 10
# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation.
This means that
# the standard Auth/DBMAuth methods can be used for
access control. The
# user name is the `one line' version of the client's
X.509 certificate.
# Note that no password is obtained from the user. Every
entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables:
SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded
certificates of the
# server (always existing) and the client (only existing
when client
# authentication is used). This can be used to import
the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*'
environment variables.
# Per default this exportation is switched off for
performance reasons,
# because the extraction step is an expensive operation
and is usually
# useless for serving static content. So one usually
enables the
# exportation for CGI and SSI requests only.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation
handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant
shutdown
# approach is that mod_ssl sends the close notify alert but
doesn't wait for
# the close notify alert from client. When you need a
different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is
closed, i.e. no
# SSL close notify alert is send or allowed to received.
This violates
# the SSL/TLS standard but is needed for some brain-dead
browsers. Use
# this when you receive I/O errors because of the
standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection
is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for
the close notify
# alert of the client. This is 100% SSL/TLS standard
compliant, but in
# practice often causes hanging connections with
brain-dead browsers. Use
# this only for browsers where you know that their SSL
implementation
# works correctly.
# Notice: Most problems of broken clients are also related to
the HTTP
# keep-alive facility, so you usually additionally want to
disable
# keep-alive for those clients, too. Use variable
"nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to
workaround
# their broken HTTP/1.1 implementation. Use variables
"downgrade-1.0" and
# "force-response-1.0" for this.
