The user_id, AFAIK, must be specified, but I doubt that it is used
anymore. If I understand things correctly, it was used to prevent some
hosts from connecting to server. But one has to check the Firebird sources.

Via TCP or via local protocol? In other words, do you use 'localhost' in
connection string?

Can you please create a bug report for this problem, so it won't be
forgotten?

And for this one a bug report, please :)

Thanks!
