[Firebird-net-provider] Your login SYSDBA is same as one of the SQL role name

[Marco <mar...@To...>]

Hi,
	i'm new to firbird and i try to start from the embedded version.
I have to work at an application released from anoter developer.

The app use this:
.NET 2.0 (C#)
Firebird .NET Provider 2.0
Firebird Embedded 1.5

I try to connect to some Firebird DB File not created by me.
The connection string is like this: "ServerType=1;User=SYSDBA;Password=masterkey;Dialect=3;Database=C:\DB.fdb"

Fore meny DB it wroks fine but for other DB the connecion rise this exception:

"Your login SYSDBA is same as one of the SQL role name. Ask your database administrator to set up a valid Firebird login."

Where is the problem? I' have read embedded firebird 1.5 not use autentication for DB.
Can you help me?

Thanks

Marco
