Other domain member servers
For other systems, AuthLite software may need to be installed if AuthLite users will be logging on interactively to the system, but generally not otherwise. For example you do not need to install software on your back-end Exchange servers, because the actual logon is performed elsewhere.
But in certain cases AuthLite must be installed. In the case of NetMotion Mobility, AuthLite must be on the server to properly parse incoming requests where the password and OTP are included together in the same field.
