Also, when in FIPS 140 mode, hostname verification for TLS cannot be turned off so if you are using
`*.verification_mode: none` , you'd need to mute the test in fips mode.

When using TLS, ensure that private keys used are longer than 2048 bits, or mute the test in fips mode.

==== Password hashing algorithm

Test clusters are configured with `xpack.security.fips_mode.enabled` set to true. This means that
