.The Ceph Object Gateway's S3 does not always work in FIPS mode If a secret key of a Ceph Object Gateway user or sub-user is less than 112 bits in length, it can cause the `radosgw` daemon to exit unexpectedly when a user attempts to authenticate using S3. This is because the FIPS mode Red Hat Enterprise Linux security policy forbids construction of a cryptographic HMAC based on a key of less than 112 bits, and violation of this constraint yields an exception that is not correctly handled in Ceph Object Gateway. To work around this issue, ensure that the secret keys of Ceph Object Gateway users and sub-users are at least 112 bits in length.
