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 Server 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. When a leaver no longer meets the rule that keeps an account in a target, that account is disabled or deleted on the next run.
