A database was created recently. That should be accessed only by 3 members from the project team. And all the 3 members will use the same Oracle user ID to login to the database. But the project team wants to make sure that only those 3 users should be able to login into that database. Is there anyway that I can restrict the OS users and allow the 3 OS users alonne to use the Oracle login ID.

Yes there is a way with database trigger but why not one account per user?
Why do they have to share the same login?

Their application depends on a particular schema. Hence they need to work on the same.

You mean the application has the schema name hard coded in accesses to the database?

If you have code that does not reference the schema explicitly, you can use an "after logon" trigger to change the current schema :
create or replace trigger use_appuser_schema 
  after logon on realuser.schema
  begin
    execute immediate 'alter session set current_schema = appuser';
  end;
/
Once "realuser" logs on, if he executes
select * from mytable;
the code will reference appuser.mytable. However,
select * from user_tables;
will still list the tables of which "realuser" is the owner!
