There are two data transfer channels between the Identity Vault and the connected application:
Publisher Channel: Transfers data and events from the connected application to the Identity Vault. The Sentinel Identity Tracking driver does not support this channel.
Subscriber Channel: Transfers data and events from the Identity Vault to the connected application. The Sentinel Identity Tracking driver supports only data transfers from the Identity Vault to Sentinel. Communication is one-way only.
The Subscriber channel does the following:
Watches for additions and modifications to the Identity Vault objects.
Makes changes to Sentinel's internal representation of Identities and Accounts that reflect those changes.
