Hello,
I would suggest using either the AD Import utility, or the Kentico Import Toolkit.
The
Kentico Active Directory Import Utility is a standalone Windows application which allows importing of users and groups (roles) from Active Directory (AD) into Kentico CMS and assigning users to roles depending on AD settings. The application also provides the possibility of updating already imported users and roles so that their properties are the same as in the current AD
The
Kentico Import Toolkit is an external utility which enables import of data from external sources into Kentico CMS. As a source of data, you can use:
•MS SQL database
•XML file
•CSV file
•XLSX file
Best Regards,
Edward Hillard
