Consider the following scenario:
- DirectAccess is configured to use One Time Password (OTP) support.
- Multiple OTP certification authorities are defined, or multiple OTP RADIUS servers are defined. (Or, multiple OTP certification authorities and multiple OTP RADIUS servers are defined.)
- One or more (but not all) of the OTP certification authorities or OTP RADIUS servers are unavailable.
This is a known issue. When at least one OTP certification authority server or OTP RADIUS server is reachable, you should receive a warning message instead of a critical error condition.
Even though an error condition is reported instead of a warning, OTP authentication will continue to work as long as there is at least one reachable OTP certification authority server or OTP RADIUS server.
