The CSV directory integration is a lightweight out-of-the-box option that enables you to build custom integrations for on-premises systems using the Okta On-Premises Provisioning agent. Organizations commonly use CSV files containing user identities. Using the agent, Okta can ingest these files on a recurring basis, importing users and their attributes into Okta. You can expect much of the functionality available in other Okta profile masters such as Workday or Active Directory, which includes scheduled imports, attribute level mastering, matching rules, and a rich profile of user attributes.
