when choosing any authorization mechanism

      sasl:
        enable: true
        username: "user"
        password: "Pass"
        mechanism: "sha256" # or sha512

the default mechanism plain is always used

if you change the line
Mechanism string yaml:"mechanism" default:"plain"
to
Mechanism string yaml:"mechanism" default:"sha256"
authorization with the sha256 mechanism is successful
