An Import connector can be run manually from the Identity Governance portal or at specific times using the scheduler.
There are subtle differences between the two.
What is the difference between running an import connector manually from the Identity Governance portal and the scheduler?
The main difference is the locale settings.
When running the import connector thorough the portal, the locale is set to that of the web browser (Chrome, Internet Explorer and so on).
So all strings are localized to that of the user who runs the import.
The scheduler is server side and has no notion of a web browser or locale of user. So all strings are English only (or what the EurekifyBaseWebApplication.properties contains.)
