You can tell lws to drop privileges and take on a noprivileged uid and 
gid just by setting the context creation info .uid and .gid


It implies you start your app as root.  The transition to the different 
uid + gid happens after the vhost protocol init, which allows you to 
open / create / modify things still as root in your 
LWS_CALLBACK_PROTOCOL_INIT.  This is very convenient for opening 
logfiles or whatever in directories that are only root-accessible, and 
still be able to use the fd after the privileges to do that have gone.

AFAIK I don't have any use for PAM + lws.

What would you actually use it for?
