How to deprovision AD account and keep it in the Metavers?

Hi,

I need to Deprovision AD account and keep them in the Metavers. How do I do that with Extensions? Pleas explain the logic of things:

When / how is the 'Public Function Deprovision(ByVal csentry As CSEntry) As DeprovisionAction Implements IMASynchronization.Deprovision' called? What is triggering it? How?
