Hello all

in these days i am working with Interbase7 and Delphi6. I am going to make
a project that should have the user authentication to enter the program.

I know that Interbase itself has user managament control. It is already
keeping user informations in its admin.ib database (isc4.gdb for old
versions of IB).

I just want to know that what is the best way to make the user managament
interface. I want to give some abilities to the admin user of the program
to add, delete user or edit the user rights through the program interface.

Since interbase has its own tables that keeps this informations, it seems
its not logical to make one extra table to keep user informations and rights.
am i right???

Actually it is easy to make managament of the rights by using GRANT or
REVOKE statements. But how can we show the already given rights in our
program? How can we add new user? We can add new user by inserting new
tuples tu the admin.ib (or isc4.gdb) but how can we specify the password?
what is the encription method of the interbase??
