Getting UserInfo data out of Sharepoint via OPENROWSET

Question

The query below returns most of the data from the SharePoint list that my customers want:

    SELECT * 
    FROM OPENROWSET ('Microsoft.ACE.OLEDB.12.0',
                     'WSS;IMEX=1;RetrieveIds=Yes;
                      User id=abc1;Password=xxxxxxx;
                      DATABASE=http://abcdefg/HijkLMno/;LIST=Whatever;',
                     'SELECT * FROM LIST') B

The issue is I need to join the local SharePoint User IDs from the UserInfo table. How do I construct the DATABASE= string and use OPENROWSET to get the ID, names, etc...?

PS I must use OPENROWSET; Please do not suggest i query these tables directly as I cannot.
