[SQL2000] permissions to use view based on tables from many databases

Hi
I have two databases: Customers and Operations. In Customers database I have
made a view based on a few tables from both Customers and Operations (left
join - customers without any operations). In the same database (Customers) I
have created a stored procedure based on the view. Finally I'd like to give
to some users permission only to exec the stored procedure.
Have I to add the users to Customers? If yes, please describe me how to
limit the users privileges only to execution the stored procedure (no rights
to open tables or view from Customers).
Regards,
Grzegorz
Ps. I had sent the post on microsoft.public.sqlserver.security, but I had no
answer.By default when you add a user they do not have any permissions to do
anything. So just make sure you don't add them to any of the server or
database roles. Then simply GRANT them execute permission on that sp.

but it doesn't work when tables are in two databases. If user have no rights
to read source table from other database SQL Server shows error:
"SELECT permission denied on object 'CustomersData', database 'Customers',
owner 'dbo'."

specify rights on the other tables. Is Cross database Ownership chaining
turned on?

in case of stored procedure the there's a check made if the user has
the right to execute a procedure. Thus it's possiblie to allow a user to
execure a procedure and e.g. display a subset of data without allowing
to read tables content. Up to sp3 it was valid for the whole server.
From sp3 you've got to set cross-databse chaining explicitly.
