But what is the advantage of windows authentication against no
authentication? When a user is logged on a windows system no further
authentication is needed to connect to a firebird database. So why use
windows authentication and not just an option for example 'unsecure
connect' or something similar? And with that option no further
authentication is needed too.
Sorry, but the sense escapes me, why the windows authentication is used.
