The SISfm page database/accessGroups.aspx is available to show the access security that is currently in use.
Initially this shows a table of counts, with a row for each access group in use, and a column for each database table that has any access groups defined.
Selecting a cell toggles between the count and a list of the items being counted, selecting the group of a row or the heading of a column does this for all cells of the row or column, selecting the top left Group cell does this for all cells. This does not include the TOTALS row, for which the same applies and the items being counted are followed by the group there.
Access groups assigned to the current user are marked with an asterisk.
