I have found 2 articles on how to configure an Apache web server for CAC card authentication. The 2 articles are
https://www.dwheeler.com/essays/apache-cac-configuration.html
https://wiki.nps.edu/display/~mcgredo/Apache+Configuration+for+CAC+Card+Authentication
both these articles have step of a shell script that downloads the CA certs using the the following wget link commands
script 1
wget http://dodpki.c3pki.chamb.disa.mil/rel3_dodroot_1024.p7b
wget http://dodpki.c3pki.chamb.disa.mil/rel3_dodroot_1024.p7b
wget http://dodpki.c3pki.chamb.disa.mil/rel3_dodroot_2048.p7b
wget http://dodpki.c3pki.chamb.disa.mil/dodeca.p7b
wget http://dodpki.c3pki.chamb.disa.mil/dodeca2.p7b
script 2
wget http://dodpki.c3pki.chamb.disa.mil/dodeca2.cac
wget http://dodpki.c3pki.chamb.disa.mil/rel3_dodroot_2048.cac
wget http://dodpki.c3pki.chamb.disa.mil/dodeca.cac
Does anyone have the current working links to download the DoD CA Certs in p7b or cac format
