But how could I revert it back?
# I saw that page, probably I did something wrong, which makes it does not work.
# Here ca.crt is ca bunlde and include Root and intermediate cert provided by Comodo?
ipa-cacert-manage -p DM_PASSWORD -n NICKNAME -t C,, install ca.crt
and what NICKNAME is it suppose to be?
#
Does mysite.crt include 4 files or just 3 files?
3 files are provided by comodo, and the rest is server.crt signed by comodo.
Sign, I spend all day long on it, quite frustrated. :)
