Firebird keeps track of activity in terms of connections and transactions, which are created dynamically and

are unique to a connection or transaction.  User login information is used only for granting (or denying) access 

for security purposes.  What this means is that you're not going to corrupt the database or interfere with other 

connections' work if everybody uses the same login criteria.  The problem comes when you actually want to 

grant (or deny) access to some people and not to others.  In that case, you should have different user names 

for different users, or create classes of user with a single user name and s single set of privileges.

Good luck,
