Scott C Gray commented on RANGER-842:
-------------------------------------

I agree with [~bolke], I have never seen a system without PAM other than, 
maybe, embedded systems.

How are things progressing with the updates to separate the PAM and Unix auth?  
If you would like help testing, please let me know, I have an environment that 
is in need of this work and can help out if needed.

> 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 This way of authenticating is somewhat outdated as any recent 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
