# Test setup
#
# This test needs a configured CA behind it in order to work properly
# It currently specifically tests for a self-signed CA but there is no
# reason the test wouldn't work with a dogtag CA as well with some
# additional work. This will change when selfsign is no longer the default CA.
#
# To set it up grab the 3 NSS db files from a self-signed CA from
# /etc/httpd/alias to ~/.ipa/alias. Copy /etc/httpd/alias/pwdfile.txt to
# ~/.ipa/alias/.pwd. Change ownership of these files too. That should do it.
