About the Local Authenticator
The Local Authenticator is a service that provides Dragon clients with Active Directory single sign-on authentication.
The Local Authenticator validates Dragon client credentials when the clients attempt to connect to NMC server, and
then passes the validate credential call to the cloud NMC server to create a session.
You must install the Local Authenticator to use single sign-on with the Nuance-hosted cloud NMC server. You do not
need the Local Authenticator if you're hosting your own NMC server on-premise.
Install the Local Authenticator on a local server that is accessible to both NMC server and your Dragon clients. You
must have Administrator privileges on the server where you are installing the Local Authenticator.
For software system requirements for the Local Authenticator, see “Software requirementsSingle sign-on” on page
