Selvamohan Neethiraj commented on RANGER-842:
---------------------------------------------
I am currently trying out the option to create two executables - One for who
uses traditional model and new one for who uses PAM authentication. I will
update the details within next couple of days.
Regarding system without PAM, I am just really worried about breaking existing
ranger users who may have systems that does not have PAM libraries and will
cause the upgrade to break their existing model. So, I really like the two
executable model - where the PAM based executable is used only if the user
selects PAM authentication.

> Ranger currently uses shadow based authentication if configured for unix
> authentication. This way of authenticating is somewhat outdated as any recent
> Linux system (and many of the BSDs) have PAM available. PAM allows multiple
> authentication sources and also does authorization.
> Ranger should be able to use PAM for authentication
