%description
OpenVPN is an SSL VPN solution which can accommodate a wide
range of configurations, including remote access, site-to-site VPNs,
WiFi security, and remote access solutions with load
balancing, failover, and fine-grained access-controls.

OpenVPN implements OSI layer 2 or 3 secure network extension using the
SSL/TLS protocol, supports flexible client
authentication methods based on certificates, smart cards, and/or
2-factor authentication, and allows user or group-specific access
control policies using firewall rules applied to the VPN virtual
interface.

OpenVPN is not a web application proxy and does not operate through a
web browser.

%package down-root-plugin
Summary:        OpenVPN down-root plugin
Group:          Productivity/Networking/Security
Requires:       %{name} = %{version}

%description down-root-plugin
The OpenVPN down-root plugin allows an OpenVPN configuration to call a
down script with root privileges, even when privileges have been
dropped using --user/--group/--chroot.

This module uses a split privilege execution model which will fork()
before OpenVPN drops root privileges, at the point where the --up
script is usually called.  The plugin will then remain in a wait state
until it receives a message from OpenVPN via pipe to execute the down
script.  Thus, the down script will be run in the same execution
environment as the up script.

%package auth-pam-plugin
Summary:        OpenVPN auth-pam plugin
Group:          Productivity/Networking/Security
Requires:       %{name} = %{version}

%description auth-pam-plugin
The OpenVPN auth-pam plugin 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 plugin uses a split privilege execution model which will function
even if you drop openvpn daemon privileges using the user, group, or
chroot directives.
