Accessing VPN using DUO append mode locking users out
We are using RRAS and DUO for out 2FA. Some users have older phones, so we have some hardware tokens for them. We are trying to use those tokens using append mode with their password. They are able to successfully connect, but within a minute their accounts are locked out. I have disabled credential manager from storing any values. Its like windows is trying to reconnect to drives with the new credentials.
Using append mode example:
Hardware token: 123456789
So when logging in the user enters in their username, and for the password they enter Secure,123456789
DUO has been of no support. We are thinking it might be something in our configuration file, or maybe there is something else on the server on our side that we need to modify. Has anyone else run into this, or have a solution?
