    Just did a clean install of the latest pfSense-CE-2.5.0-DEVELOPMENT-amd64-20190322-1846.iso
    Restored a backup config from 2.4.5.
    Had issues with limiters fq_codel (will post in the relevent thread later) but got around them.
    Now i'm having issues with my restored OpenVPN server. (TLS/SSL + User Auth)
    Android client is now coming up with User authentication failed. Confirmed user and pass is right by logging into webgui with the user and it worked.
    Set OpenVPN server to just TLS/SSL and the Android client could connect successfully.
    When setting back to (TLS/SSL + User Auth), the following lines appear in the logs.

    Mar 24 00:09:36 	openvpn 	94261 	PLUGIN auth-script: Deferred handler using script_path=/usr/local/sbin/ovpn_auth_verify_async

    Not sure if the status=2 is causing the issue.
    Further down in the log...

      Having exactly the same problem. Doesn't matter if upgrading or clean installing with config restore.

      Because I am lazy, I opened a bug report with exactly what you have posed here: https://redmine.pfsense.org/issues/9427 :)

        Same here. I have a more convoluted setup however. I use FreeRadius with OTP enabled which further authenticates with Duo. (I know it's crazy, I did it more to see if it would work) I've tried with local authentication also with the same results. One thing I did notice is that in 2.5 "ecdsa-with-SHA1" is not a option for Auth Digest Algorithm. That is what I had it set in 2.4.5. I did experiment with changing it to SHA1 (which is available) but received the same authentication error.

            Having same issue. Upgraded to latest 2.5 after 2.45 DEV build corrupted. Restored backup. Everything seems to work but OpenVPN with local AUTH. Recreated OpenVPN server and firewall rules, exported new clients and installed. Still get "AUTH: Received control message: AUTH_FAILED". Can login locally with user/pass combination. OpenVPN log shows user authenticated.

              This should be fixed now, was an output change in one of the auth scripts.
