When a user logs in, NetWitness Platform first attempts to authenticate locally. If no local user is found, and External Authentication configuration is enabled, an attempt is made to authenticate externally.
External authentication allows users who do not have an internal NetWitness Platform user account to log on to NetWitness Platform and receive role-based permissions.
NetWitness Platform supports two methods of external authentication, Active Directory and Pluggable Authentication Modules (PAM). The below procedures describe how to configure and test each method.
