There is already such an option with another project that especially aims at educational environments. It has Samba4 fully implemented and all modules have Samba auth integrated.
Ultimately it would be a HUGE option if NS has the same options. Including Samba4 and educational modules like Chamilo/Moodle/Xibo/Schooltool/Xerte etc...
Maybe the NS project can learn from the LinuxSchools project on how the several tools and applications are implemented. (why invent the wheel another time) The major differences between the 2 projects:
NS: template based, CentOS based
Karoshi server: bash scripting based, Ubuntu LTS based.
