Most people on the list only grudgingly use MySQL and so most are not so
well aware of the limitations of MySQL's security model.

MySQL has no concept of group memberships or group permissions (or the
more complex role permissions).  The permissions are simply at the level
of the individual user.  When I have coded complex apps on MySQL, I have
sometimes found it necessary to emulate this level of permission so that
the permissions can be "compiled" down to individual permissions on the
tables.  It is a real pain sometimes.
