OpenVPN w/RADIUS & AD Authentication Intermittent
-
My OpenVPN connection is VERY intermittent. Everything is configured properly as per the cookbook and when I test authentication it sometimes passes, sometimes fails. I've checked the RADIUS server (Windows 2008 r2) logs and show audit failures and success when using the same exact credentials. If you need logs please let me know…but based on this little bit of information I was hoping someone could provide any kind of feedback.
I'm wondering if it's an issue with my RADIUS server? I haven't changed any configs and it used to work before, but if I have to I will recreate the entire server.

Sounds like the RADIUS server to me. Perhaps there is something in NPS on server 2008 that is causing the logins to be rejected.
It sounds like it should be logging more than what you're seeing.
