User account requirements

Unica Discover user accounts include account permissions, NT authentication, and Network Capture Application accounts.

Account permissions

As a recommended best practice, give any account used by a Windows-based Unica Discover service Local System permissions on the server.

Using non-local system accounts for running Unica Discover software is not supported. Running Unica Discover services with permissions other than Local System permissions might cause problems, such as failures to connect, write errors, and unexpected time-outs.

NT authentication

When NT authentication is enabled for the Unica Discover system, Unica Discover services must run under an NT domain account with appropriate privileges. Additional configuration may be required.

Network Capture Application (DNCA) accounts

The Unica Discover DNCA runs on the Linux operating system. During DNCA installation, the dncauser account is created, which is used for running all DNCA services.
