#REGTEST_TYPE=devel

# This reg-test tests the client auth feature of HAProxy for both the backend
# and frontend section with a CRL list
#
# This reg-test uses 2 chained listeners because vtest does not handle the SSL.
# Test the frontend client auth and the backend side at the same time.
#
# The sends 3 requests one with a correct certificate, one with an expired one and one which was revoked.
# The client then check if we received the right one with the right error.
#
# Certificates, CA and CRL are expiring in 2050 so it should be fine for the CI.
#
# Detail about configuration is explained there:
# https://www.haproxy.com/blog/ssl-client-certificate-management-at-application-level/
