What should a SFDC Type = User filter find?

[Anonymous]

I assumed that the SFDC Type = User filter would display all of our SFDC Users, but this smart list is empty.  What does this filter do?

Not 100% sure, but maybe it's related to SFDC Partner / Customer portal (and not "Regular" SFDC users).
I have found this discussion: https://community.marketo.com/MarketoDiscussionDetail?id=90650000000PHXmAAO
although it would be great to get a confirmation from Marketo and apply this rule to all SFDC users.
