> FIPS doesn't allow using MD5 algorithm, so it should be disabled at all 
> times. When we create SASL client there's a fallback code path: if Kerberos 
> doesn't work for some reason, we try to use DIGEST-MD5 mech instead. We 
> already have a fips-mode property, so let's disable this code patch if the 
> property is enabled.
