I have a PC with Firebird installed and a Windows User Guido, who is
member of the group User, not Main User or Power User. If I login with
Guido at the PC, I can't connect to a Firebird DB via local connection
only via TCP/IP. The DB is in the folder
C:\Dokumente und Einstellungen\guido\Eigene Dateien
a folder, in which Guido has full access. I can connect to the DB with
the connection string
w2k:C:\Dokumente und Einstellungen\guido\Eigene Dateien\db.fdb
but when I try the local connection
C:\Dokumente und Einstellungen\guido\Eigene Dateien\db.fdb
I get the error message 'Unavailable Database'.
Any ideas, what rights the user Guido is missing?

Regards

Guido
