[AccessD] Assign Jet User Roster Recordset to Form

I'm using A2002 and ADO 2.5.  For some reason I have a mental block
today.  I want to set the Jet User Roster recordset returned from
OpenSchema to a form's recordset, but I get an error 7965, The object
you entered is not a valid Recordset property  I used an adUseServer
cursor on the connection, and in fact I get the recordset back.  What am
I missing here?  I *never* do this, so I'm rusty.
