There are two data transfer channels between the Identity Vault and GroupWise: Subscriber channel and Publisher channel. The driver supports communication in one-way only on Subscriber channel.
Subscriber Channel: Transfers data and events from the Identity Vault to the GroupWise system.
The Subscriber channel controls data transfer as follows:
It monitors the Identity Vault for new objects and any change to the existing objects.
It sends the relevant changes to the driver shim to be executed in the GroupWise system.
Publisher Channel: This channel is not supported for the driver. However, the driver automatically synchronizes EMail Address and Internet EMail Address attributes on the channel. A user add event on the Subscriber channel fetches these attributes from the GroupWise system that in turn trigger a Publisher event which synchronizes the attributes to the Identity Vault unless the attributes are not disabled in the driver filter.
IMPORTANT:Some Identity Vault attributes contain multiple values for which GroupWise allows only one value. When you modify a multivalued attribute in the Identity Vault, the driver overwrites the value for this attribute in GroupWise. If you delete any value from a multivalued attribute from the Identity Vault, the driver deletes the attribute from GroupWise.
