Joiner, mover, leaver from the HR system of record
The situation
New hires wait days for an account. Transfers keep old group memberships. Leavers keep working credentials because the HR change never reached the directory.
With Identity Mesh
Import from Workday, a SQL HR database, or a file feed, then flow employees into Active Directory and Entra ID with transform rules for usernames, OUs, and group assignment. Delta sync picks up only what changed. A leaver's precondition failing disables or deletes the target account on the next run.
