The Data Insight user definition requires a domain name. The Data Loss Prevention credential setup does not have a field for a domain name. How do I set the domain name?
In the System > Settings > Credentials "Access Username" or in the System > Settings > Date Insight > Configure "Username" you specify the domain name like this:
The domain name must match the domain name in the Data Insight user definition. The domain must have that user defined and the password must match.
