Config error on Ubuntu 14.04 

Hey, thanks for the prompt resolution on the previous bug, I was about to have a look at it myself but you beat me to it.

I've come across another issue (note - replaced my domain name):

    Notice: /Stage[main]/Main/Node[vpn.blah.net]/Openvpn::Server[vpn.blah.net]/Exec[create crl.pem on vpn.blah.net]/returns: Using configuration from /etc/openvpn/vpn.blah.net/easy-rsa/openssl.cnf
    Notice: /Stage[main]/Main/Node[vpn.blah.net]/Openvpn::Server[vpn.blah.net]/Exec[create crl.pem on vpn.blah.net]/returns: error on line 198 of config file '/etc/openvpn/vpn.blah.net/easy-rsa/openssl.cnf'
    Notice: /Stage[main]/Main/Node[vpn.blah.net]/Openvpn::Server[vpn.blah.net]/Exec[create crl.pem on vpn.blah.net]/returns: 140001620666016:error:0E065068:configuration file routines:STR_COPY:variable has no value:conf_def.c:618:line 198
    Error: . ./vars && KEY_CN='' KEY_OU='' KEY_NAME='' openssl ca -gencrl -out /etc/openvpn/vpn.blah.net/crl.pem -config /etc/openvpn/vpn.blah.net/easy-rsa/openssl.cnf returned 1 instead of one of [0]
    Error: /Stage[main]/Main/Node[vpn.blah.net]/Openvpn::Server[vpn.blah.net]/Exec[create crl.pem on vpn.blah.net]/returns: change from notrun to 0 failed: . ./vars && KEY_CN='' KEY_OU='' KEY_NAME='' openssl ca -gencrl -out /etc/openvpn/vpn.blah.net/crl.pem -config /etc/openvpn/vpn.blah.net/easy-rsa/openssl.cnf returned 1 instead of one of [0]

Line 198 was this:

    subjectAltName=$ENV::KEY_ALTNAMES

I commented it out and got another one:

    Notice: /Stage[main]/Main/Node[vpn.blah.net]/Openvpn::Server[vpn.blah.net]/Exec[create crl.pem on vpn.blah.net]/returns: error on line 220 of config file '/etc/openvpn/vpn.blah.net/easy-rsa/openssl.cnf'

Line 220 is the same:

    subjectAltName=$ENV::KEY_ALTNAMES

Commented out again and worked. Let me know if I can provide anything else to assist.
