Bolke de Bruin commented on RANGER-842:
---------------------------------------

You could do that. However I would challenge you to find a Linux install that 
does not have PAM available. The large distributions all include it as it is 
the standard for authentication on this platform.  

Obviously if you supply a precompiled rpm/deb one does not need the development 
headers installed.

> 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 This way of authenticating is somewhat outdated as any recent 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
