-openvpn-auth-pam
-
-SYNOPSIS
-
-The openvpn-auth-pam module implements username/password
-authentication via PAM, and essentially allows any authentication
-method supported by PAM (such as LDAP, RADIUS, or Linux Shadow
-passwords) to be used with OpenVPN. While PAM supports
-username/password authentication, this can be combined with X509
-certificates to provide two indepedent levels of authentication.
-
-This module uses a split privilege execution model which will
-function even if you drop openvpn daemon privileges using the user,
-group, or chroot directives.
-
-BUILD
-
-To build openvpn-auth-pam, you will need to have the pam-devel
-package installed.
-
-Build with the "make" command. The module will be named
-openvpn-auth-pam.so
-
-USAGE
-
-To use this plugin module, add to your OpenVPN config file:
-
- plugin openvpn-auth-pam.so service-type
-
-The required service-type parameter corresponds to
-the PAM service definition file usually found
-in /etc/pam.d.
-
-This plugin also supports the usage of a list of name/value
-pairs to answer PAM module queries.
-
-For example:
-
- plugin openvpn-auth-pam.so "login login USERNAME password PASSWORD"
-
-tells auth-pam to (a) use the "login" PAM module, (b) answer a
-"login" query with the username given by the OpenVPN client, and
-(c) answer a "password" query with the password given by the
-OpenVPN client. This provides flexibility in dealing with the different
-types of query strings which different PAM modules might generate.
-For example, suppose you were using a PAM module called
-"test" which queried for "name" rather than "login":
-
- plugin openvpn-auth-pam.so "test name USERNAME password PASSWORD"
-
-While "USERNAME" "COMMONNAME" and "PASSWORD" are special strings which substitute
-to client-supplied values, it is also possible to name literal values
-to use as PAM module query responses. For example, suppose that the
-login module queried for a third parameter, "domain" which
-is to be answered with the constant value "mydomain.com":
-
- plugin openvpn-auth-pam.so "login login USERNAME password PASSWORD domain mydomain.com"
-
-The following OpenVPN directives can also influence
-the operation of this plugin:
-
- client-cert-not-required
- username-as-common-name
-
-Run OpenVPN with --verb 7 or higher to get debugging output from
-this plugin, including the list of queries presented by the
-underlying PAM module. This is a useful debugging tool to figure
-out which queries a given PAM module is making, so that you can
-craft the appropriate plugin directive to answer it.
-
-CAVEATS
-
-This module will only work on *nix systems which support PAM,
-not Windows.
