Description

Motivation

Render a well structured and mesos-alike naming and folder tree. This shall be similar to what we know from the awesome! containerizer structure.

Folder Structure

For the flat-file Authenticator Module but also for authentication as a whole, I would like to propose the following structural changes:

• move authenticator.hpp out of sasl/
• create a new authentication/
  • put the module interface here and name it authenticator.hpp
• create a new authentication/cram_md5
  • put the default/module implementation here and name it authenticator.hpp
  • mind that I am proposing cram_md5 instead of sasl due to the fact that cyrus-sasl2 offers many more mechanisms but our current default (CRAM-MD5) and further dividing the tree into sasl and non-sasl based authentications may be too verbosive/bloated.

Module Naming

Following the module naming scheme, I would like to propose org_apache_mesos_authenticator_crammd5 to be used for our first/default Authenticator. Mind that in this case I did not reflect the folder tree into this reverse domain alike description as I find it more intuitive to have the module before the kind - objections?

Library Naming

Given that we will also add an authenticatee to this library, a proper name would be
libauthentication_crammd5.so/dylib
