I have setup a POC using Windows Multi-Factor Authentication (i.e. Phonefactor Classic - my term) as a RADIUS authentication server to one of our UAG trunks. For the most part, everything works as expected. However, I have a few users that have tried switching to the text messaging type of MFA authentication with some issues that have to do with timing.
- The user enters their uid/pwd at the UAG logon screen
- UAG then attempts to authenticate with the RADIUS (Phonefactor) server
- The user is still waiting at the logon screen.
- If the text message doesn't come immediately, then the user gets an "Authentication Failed" type of message from UAG
What I need to be able to do is increase that time that UAG waits on the response from the RADIUS server, but I can't seem to find such a setting.
Any ideas?
