# Synchronize existing users

When the provisioning connector updates users between the data store and PingID SDK, it synchronizes users that share an identical `Username` attribute.

Example scenario:

* In PingID SDK, Janet's `Username` is `jsmith`.

* In your data store, Janet's `sAMAccountName` is `jsmith`.

* On the **Attribute Mapping** screen, you map the `Username` attribute to `sAMAccountName`.

* When the provisioning connector runs, the data store user is provisioned with a `Username` of `jsmith`. That matches Janet's existing `Username` in PingID SDK, so her information in the data store is synchronized to her PingID SDK account.
