OpenVPN with LDAP example
|
|
#########################
|
|
|
|
Configuration AD and a windows server
|
|
=====================================
|
|
|
|
We aim to configure LDAP authentication between the VYOS router and Windows Server 2019 (role: Active Directory) when our customers connect to our privet network using the OpenVPN client.
|
|
Using the general schema for example:
|
|
|
|

|

|

|
|
|
|
.. code-block:: none
|
|
|
|
VyOS - the main OpenVPN server
|
|
Winserver - windows server with role Active Directory
|
|
Win10-PC - OpenVPN customer with LDAP authentication
|
|
|
|
First, we need to configure the AD service and create two accounts. One account for the LDAP adapter built into the VYOS router and a second even account for our test client.

Configuration VyOS router
|
|
=========================
|
|
|
|
Make the configuration file for the LDAP plugin.
|
|
|
|
.. code-block:: none
|
|
|
|
vyos@vyos:~$ sudo cat /config/auth/ldap-auth.config
|
|
<LDAP>
|
|
URL ldap://10.217.80.58
|
|
BindDN userldap@corp.vyos.com
|
|
Password YourPass
|
|
Timeout 15
|
|
TLSEnable no
|
|
FollowReferrals no
|
|
</LDAP>
|
|
<Authorization>
|
|
BaseDN "DC=corp,DC=vyos,DC=com"
|
|
SearchFilter "sAMAccountName=%u"
|
|
RequireGroup false
|
|
</Authorization>
|
|
|
|
|
|
**This specific example is for a windows server 2019**:
|
|
|
|
* URL ldap://10.217.80.58 - The URL of your LDAP server
|
|
* BindDN userldap@corp.vyos.com - The BindDN of the users' directory
|
|
* BaseDN "DC=corp,DC=vyos,DC=com" - In the block <Authorization> notice your domain
|
|
|
|
Make the main config for VyOS like VPN and Authorization server:
|
|
|
|
.. code-block:: none
|
|
|
|
set interfaces ethernet eth0 address 'dhcp'
|
|
set interfaces openvpn vtun10 local-port '1194'
|
|
set interfaces openvpn vtun10 mode 'server'
|
|
set interfaces openvpn vtun10 openvpn-option '--plugin /usr/lib/openvpn/openvpn-auth-ldap.so /config/auth/ldap-auth.config'
|
|
set interfaces openvpn vtun10 persistent-tunnel
|
|
set interfaces openvpn vtun10 protocol 'udp'
|
|
set interfaces openvpn vtun10 server push-route 192.168.0.0/16
|
|
set interfaces openvpn vtun10 server subnet '10.23.1.0/24'
|
|
set interfaces openvpn vtun10 tls ca-cert-file '/config/auth/openvpn/ca.crt'
|
|
set interfaces openvpn vtun10 tls cert-file '/config/auth/openvpn/central.crt'
|
|
set interfaces openvpn vtun10 tls crl-file '/config/auth/openvpn/crl.pem'
|
|
set interfaces openvpn vtun10 tls dh-file '/config/auth/openvpn/dh.pem'
|
|
set interfaces openvpn vtun10 tls key-file '/config/auth/openvpn/central.key'
|
|
set protocols static interface-route 10.23.0.0/20 next-hop-interface vtun10
|
|
set service ssh port '22'
|
|
|
|
Next, you need to install and configure the configuration file for the windows/Linux OpenVPN client. After connecting to the VPN servers, you will be prompted to go through LDAP authorization.
