## Symptoms

- Few Remote Access clients that do not support Multi-Factor Authentication (MFA) are able to connect to a Security Gateway even though "Allow older clients" is disabled.

## Cause

Non-default authentication settings for remote access were configured. "Allow older clients to connect to this gateway" is unchecked.

Authentication is configured under Multiple Login Options, however due to enforcement mishandling, few clients are still able to connect using different authentication scheme.
