FIM Portal Self Service User Provision Frequency

Hi All,

I have a question about fim portal self service.If a user updates their AD attributes (i.e telephone number) in the portal, how long before it appears in AD? Presumably it's dependent on a management agent run profile? If so can this be automatically triggered?

On the other hand, I assume automatic triggerring in a production environment is a bad idea due to load and frequency?

thanks
