Troubleshooting OpenVPN Authentication and Authorization 

For additional diagnostic information, you can enable Debug Level logging in the OpenVPN Access Server 'as.conf' configuration file, restart the service and review the log messages within the default "/var/log/openvpnas.log" file.

$ sudo echo "DEBUG_AUTH=true" >> /user/local/openvpn_as/etc/as.conf 
$ sudo service openvpnas restart 

When troubleshooting is complete, edit the configuration file to comment out the DEBUG reference, and restart the service to return to normal operation.

#DEBUG_AUTH=true 
$ sudo service openvpnas restart
