Nuance Management Center Server Installation and Client Configuration Guide
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 the Nuance-hosted cloud 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 the 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 requirements—Single sign-on
for Cloud NMC server” on page 36.
