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: The driver synchronizes limited attributes for User and Group objects to the Identity Vault. For a User object, the Publisher channel synchronizes EMail Address and Internet EMail Address attributes. For a Group object, it synchronizes only Member attribute. If you need to stop synchronizing these attributes, customize the driver filters.
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.
