nss_curl

This is a NSS module that uses cURL to fetch JSON from the remote host via http(s) and use that JSON to provide account information to a Linux system.

Dependencies

libssl-dev
jansson-dev
libcurl4-gnutls-dev

Install

I tested the installation on Ubuntu 18.04, you will need to change Makefile maybe.

Clone git repo
Install dependencies
make
make install
Edit /etc/nsswitch.conf, add "curl" to the desired sections

passwd:         compat curl
group:          compat

Configuration

The module is configured via /etc/nss_curl.conf that is a JSON data file.

{
	"passwd": "https://example.com/users.json",
	"groups": "https://example.com/groups.json",
	"headers":[
		{"Authorization": "Basic dGVzdDp0ZXN0"}
	],
	"cache_directory": "/tmp",
	"cache_valid": 300
}

I think, keys' names are self-documented.
