I'm having some issues getting OpenVPN to work using both LDAP login and a TOTP token and hoping someone else has a solution that works.
What I've tried:
Using plugins openvpn-auth-ldap with openvpn-otp with challenge/response. This works, except that I can't get gnome-network-manager-openvpn to prompt for the challenge/reponse key in GUI (which is necessary for my Linux Mint users) - it works perfectly for Windows, though.
Recently I tried using openvpn-plugin-auth-pam with openvpn-auth-ldap, so that users would type their password+otpkey in a single string, but the issue with auth-ldap is that it doesn't filter out the last 6 digits from the password and its being rejected in the LDAP plugin. This only works with a local user database

If anyone has any solutions or suggestions, I'd love to hear from you.
Thanks in advance,
