Sorry - It looks like what I copied and paste the service status I missed the
end of the lines. It has been updated below now.

Looking for some direction on what I'm doing wrong with getting Mesos slave
authentication working. I'm getting "Failed to authenticate
slave(1)@192.168.33.10:5051: Failed to get list of mechanisms: SASL(-4): no
mechanism available: Internal Error -4 in server.c near line 1757" after start
mesos-slave on the same host. Here are my current settings:
/etc/mesos-mater files
------------------------------
authenticate = true
authenticate_slaves = true
authenticators = crammd5
credentials = /etc/mesos/mesos-config/mesos-master.passwd

I'm using principal <whitespace> secret in the mesos-master.passwd and
mesos-slave.passwd with no new line after the credentials (aka: echo -n ).
