 # Purpose: Automate host certificate generation in a domain environment
 # Package: ansible role certreq
 # History: 
-#    2017-11-22 Added ca cert chain
+#    2017-11-22 Add ca cert chain
+#    2018-04-16 Add --list and --csr options
 # Usage: in ansible role certreq
 #    Microsoft CA cert templates have permissions on them. A user must be able to "enroll" on the template.
 # Reference: ftemplate.sh 2017-10-10x; framework.sh 2017-10-09a
 #    fundamental curl statements https://stackoverflow.com/questions/31283476/submitting-base64-csr-to-a-microsoft-ca-via-curl/39722983#39722983
