Niklas Quarfot Nielsen commented on MESOS-1966:
-----------------------------------------------

The path for (3) is not clear yet, so definitely (1) for now. One decision 
while designing modules was, that Mesos would work _as is_ without modules 
(and/or until we have tested the system in prod). The isolator module works 
this way too.

> Integrate the Authenticator module

> There are some options we quickly need to decide upon:
> 1. Keep the currently existing authenticator {{sasl/authenticator.hpp}} 
> within {{libmesos}} as a default implementation. Add the {{--authenticators}} 
> flag to the master and if the user selects {{crammd5}}, use the linked in, 
> default implementation. If the user selects a different name e.g. 
> {{org_apache_mesos_authenticator_pam}}, the master will try to load a module 
> with that name and use its implementation. This is somewhat similar to what 
> Kapil has done with the Isolator module integration.
> 2. Make the currently existing authenticator become a module and thereby 
> remove it from libmesos. Add the {{--authenticators}} flag to the master and 
> ask the user to supply a module as well ( {{--modules}} ). 
> 3. Mixture of 1. and 2. Difference to 2. would be that we load the 
> authenticator module implicitly (without the user supplying the {{--modules}} 
> flag)  as soon as he has enabled any kind of authentication ( 
> {{--authenticate_slaves}} / {{--authenticate_frameworks}} ).
