We installed IM (Web UI, Provisioning Server, Directory, Manager) without FIPS 140-2 compliance turned on. Is there a method to enable FIPS compliance without re-installing all the products?
Once FIPS 140-2 support is enabled for an Identity Manager deployment, you cannot disable it. Similarly, if you install Identity Manager without enabling FIPS 140-2 support, you cannot add support at a later time.
You should also be aware that there is no way of swapping the key once installed so be sure it is never compromised or else it will need a product re-install.
