🗣 Description
This pull request leverages some recent changes in cisagov/ansible-role-freeipa-server in order to make the following changes in the configuration of the Apache server that is in front of FreeIPA:
💭 Motivation and context
The security folks are concerned that trace functionality is enabled on the Apache server that sits in front of FreeIPA. This is despite this note in the Apache documentation.
The security folks are also concerned that the same Apache server is not returning HSTS headers.
See cisagov/cool-system-internal#135 and cisagov/cool-system-internal#136 for more details.
🧪 Testing
All automated tests pass. I also built a new FreeIPA AMI for COOL staging that included these changes and verified that it functioned as expected.
