Hi!,

I've developed a database & have created users.
I've created 2 type of user-1) who can only read the
database & users of "readonly users' group. 2) super users
who are users of "admins" group- who can read, ModifY &
grant perimissions on database objects.

But the problem is: even though the read only users have
the right to only read the database object, they are able
to modify even delete records from database tables. which
I dont'. Pls. help .
