While I understand your surprise, this behaviour is normal, intentional
and DOCUMENTED. This feature is remain of old trusted host security in
InterBase. This is best known on Linux/UNIX, but not very known on
Windows (because it works only partially on NT/2000/XP, not W9X, see

On Linux/UNIX use /etc/hosts.equiv (or .rhosts etc. - see the doc) to
make a relationship between "trusted" computers, and you can log in with
your OS user identity (any, not just root. If you have root privileges,
you're equal to SYSDBA.

On Win NT/2000/XP it works (AFAIK) only for Administrator account.

To use OS identity as db level identity, you can't specify a
user/password combo on login in any way (including ISC_USER, cmd switch
