Fixed In Version: pki-core-10.3.2-3.el7
Doc Type: Enhancement
Doc Text:
Certificate System now supports setting SSL ciphers for individual installation Previously, if an existing Certificate Server had customized cipher set that did not overlap with the default ciphers used during the installation, a new instance could not be installed to work with existing instances. With this update, Certificate System enables you to customize the SSL cipher using a two-step installation, which avoids this problem. To set the ciphers during a Certificate System instance installation: 1. Prepare a deployment configuration file that includes the "pki_skip_configuration=True" option. 2. Pass the deployment configuration file to the "pkispawn" command to start the initial part of the installation. 3. Set the ciphers in the "sslRangeCiphers" option in the `/var/lib/pki/<instance>/conf/server.xml` file. 4. Replace the "pki_skip_configuration=True" option with "pki_skip_installation=True" in the deployment configuration file. 5. Run the same "pkispawn" command to complete the installation.

Description Matthew Harmsen 2016-01-29 18:44:10 UTC
This bug is created as a clone of upstream ticket:

Case being a site has customized its cipher lists (sslRangeCiphers) in server.xml throughout all CS instances.
new cipher list being a lot more stringent.

When installing new cs instance, the default ciphers does not overlap with the already-installed servers, including the Security Domain CA, hence making it not able to connect.
Workaround is to loosen the ciphers on the SD CA and possibly others required during installation; however, that is not ideal, as it requires making changes and restarting the affected servers and changing them back later.

It would make better sense to allow admin to customize the cipher list of the to-be-installed instance before the actual installation.
