I'm getting the following error (client side) when connecting to my OpenVPN server:
AUTH: Received AUTH_FAILED control message
and on the server I get thefollowing error message in teh openvpn logs:
AUTH-PAM: BACKGROUND: user 'myUsername' failed to authenticate: Module is unknown
The system was configured by another sysadmin (who is now gone) and I need to resolve this problem. So I'm not sure how this is configured, but I was told that our openvpn is authenticating against the active directory that we have using winbind.
We've recently moved our active directory server and so this is likely the problem.
- How can I confirm that openvpn is using winbind to authenticate users against our active directory?
- If I've changed the location (ip address) of the active directory server, where would I need to look to update openvpn/winbind to make this work again?
- What other information do I need to look for or provide to debug this issue?
