I set up Duo, OpenVPN/pfSense, and AD for a client recently. It's a little bit fiddly but it works quite well when it's done. Duo wants to be the AD client that authenticates on your behalf so it makes requests against your AD environment using the LDAP lookup account that you configure in your Duo config file. But since the Duo Security’s OpenVPN plugin utilizes the password field to input your method of authentication, this poses a problem to your existing PAM integration. The problem is, OpenVPN sends the same password to both plugins. For users who have signed up for two-factor authentication, connecting to vpn.mit.edu using the AnyConnect VPN client on or after January 13 will result in a failed login with the following message: ‪'You are configured for Duo two-factor authentication and must use Duo to connect through the VPN service.

Thank you for the reply. On my side, I have the same setup as you explain but I use RCDevs OpenOTP (MFA authentication server) instead of DUO security products. RCDevs provides a custom OpenVPN package who can be installed and configured very quickly. Age of wonders 3 mac download.

OpenVPN Authentication Using PAM and Duo Security It’s possible to configure with two-factor authentication utilizing PAM and phone authentication on 10.04 LTS. You just need to think like a hacker By using password concatenation with OpenVPN’s PAM plugin and Duo Security’s plugin, your password will be comma-delimited, supporting both a PAM integrated password and Duo Security’s phone authentication. Summary I wasn’t satisfied with OpenVPN’s options for two-factor authentication. I configured OpenVPN with client certificates and Active Directory password integration via pam_winbind, but I wanted better security. Knowing that it’s possible for an attacker on a compromised workstation to grab both the certificate and the user’s password (by keylogging or, depending on the OpenVPN configuration, memory scraping), I felt I needed a second out-of-band factor. This is where comes into play.

This is where comes into play. Duo has made phone authentication simple to set up, use, and manage. They’ve created an and, for most users, it’s all you need. But since the Duo Security’s OpenVPN plugin utilizes the password field to input your method of authentication, this poses a problem to your existing PAM integration. The problem is, OpenVPN sends the same password to both plugins. Therefore, simply using your existing PAM plugin with Duo’s plugin isn’t an option. Unless we make some modifications.

It's a little bit fiddly but it works quite well when it's done. Duo wants to be the AD client that authenticates on your behalf so it makes requests against your AD environment using the LDAP lookup account that you configure in your Duo config file. When the user logs in, pfSense make an auth request to your Duo proxy server via RADIUS -the Duo Proxy authenticates the users creds against AD -the Duo Proxy then sends out the push notification to Duo cloud services if the users AD credentials check out. -once the user confirms the two-factor notification the proxy server then tells the OpenVPN server that all is good and the connection process starts. Thank you for the reply.

This option will determine how often OpenVPN forces a renegotiation, thereby requiring the user to re-authenticate with Duo. This setting defaults to 3600 seconds, which means your users must re-authenticate every hour. If your user's VPN client saves the password and automatically re-authenticates with it, this may cause issues with the user receiving unexpected push notifications or their client replaying a one-time passcode. Therefore, we recommend disabling reneg-sec by setting it to 0 in your server configuration file: reneg-sec 0. Note Old versions of OpenVPN may fail to connect with reneg-sec set to 0.

Connectivity Requirements This integration communicates with Duo's service on TCP port 443. Also, we do not recommend locking down your firewall to individual IP addresses, since these may change over time to maintain our service's high availability. First Steps Please note: • Duo only integrates with OpenVPN servers that employ certificate authentication and use a unique common name (CN) in each user's cert. Support for OpenVPN deployments with password authentication may be supported in the future. • Users will provide a passcode or factor identifier (eg.

You must use the AnyConnect client to access VPN. Some information on this page was generously provided.

The number following the factor identifier identifies which enrolled device you wish to use to authentication. So, if you have two phones provisioned, you can also enter phone2, push2, etc. So, if you wanted to use Duo Push to authenticate, you would enter: username: password: push If you'd like to use a Duo passcode instead (eg. '124356'), enter: username: password: 123456 Troubleshooting Need some help?

How are updates handled for AnyConnect? • The AnyConnect VPN client will update automatically. If updates are available, AnyConnect will perform them after completing the two-factor authentication automatically. Once the update completes, you will already be connected to the VPN.

Active Directory and OpenOTP works very well together and are very easy to setup. I worked with DUO 2 years ago, but pricing for enterprise company are more interesting with RCDevs products and support/dev teams are great!! I asked for a special feature and they added it in 1 day!!! And for small company the product is free up to 40 users.

Hi All, I was able to setup OpenVPN authentication with active directory and it works great. I've looked for guides on how to configure multi-factor authenticator so users will get a phone call or push notification when they are trying to authenticate with OpenVPN but so far no luck. I've setup Duo proxy server on a windows server 2012r2 server, created the Radius client and generated a key and entered all the details in the Duo config files, restarted the Duo service, but i am still not able to get the prompt. It is related to the fact that pfsense is not able to authenticate with the radius server. My questions is: is there anyway to use AD and Duo with OpenVPN or does it have to go via Radius? So far i am not able to authenticate radius with PFsense but AD works like a charm. I set up Duo, OpenVPN/pfSense, and AD for a client recently.

A successful PAM authentication in the OpenVPN server logs will return a status=0. A status=1 is a failure. This plugin call output will looks like this: PLUGIN_CALL: POST /usr/lib/openvpn/openvpn-auth-pam.so/PLUGIN_AUTH_USER_PASS_VERIFY status=0 If you are successfully connected and your tunnel re-keys every hour, make sure your server config and client configs have matching reneg-sec statements. Otherwise, re-keying will happen with whichever one is the lowest.
