I use GDAL's ODBC driver to join to the mdb:

     CONNECTIONTYPE OGR
     CONNECTION     'G:/GeoData/Parcels/Alberta/t_505033.shp'
     DATA "SELECT * FROM t_505033 LEFT JOIN 
'ODBC:Parcels_Rural,basic'.basic ON t_505033.PID=basic.PID"

allowing me to use values from the table "basic" in the mdb for 
labeling, etc:

     LABELITEM  'LINC'
     CLASSITEM 'STATUS'

Best Regards,
Brent Fraser
