nginx-auth-saslauthd

Nginx authentication module support for LDAP, PAM or other mechanisms supported by saslauthd. Authentication requests are forwarded from nginx to a running saslauthd using its unix domain socket.

location /restricted/ {
	auth_saslauthd "restricted area";
	auth_saslauthd_socket /var/run/saslauthd/mux;
}

Installation

This module has not (yet?) been packaged. That means that you must know how to compile and install it (see nginx doc), compilation and installation is done as any 3rd party nginx module. Be sure to use the same nginx version, with e.g. git checkout release-1.18.0.

As an example, I use this (simplified) commands to build on Alpine, from the nginx source code directory:

apk add linux-headers make gcc musl-dev libaio-dev pcre-dev openssl-dev zlib-dev libxslt-dev gd-dev geoip-dev perl-dev
