Adds a KRA as an IPA\-managed service. This requires that the IPA server is already installed and configured, including a CA.
The KRA (Key Recovery Authority) is a component used to securely store secrets such as passwords, symmetric keys and private asymmetric keys. It is used as the back-end repository for the IPA Password Vault.
ipa\-kra\-install can be run without replica_file to add KRA to the existing CA.
ipa\-kra\-install will contact the CA to determine if a KRA has already been installed on another replica, and if so, will exit indicating that a replica_file is required.
The replica_file is created using the ipa\-replica\-prepare utility. A new replica_file should be generated on the master IPA server after the KRA has been installed and configured, so that the replica_file will contain the master KRA configuration and system certificates.
