Subject Connect Libreoffice Base with Firebird

I installed firebird server and libreoffice Base 6.2

On the database wizard I proceeded like:

 -Select Database Step: 

-on the Connect to an existing database dropdown menu I picked Firebird File and clicked Next 

- On the Connection settings it asks for Datasource URL (e.g. host=$host:$port dbname=$database) I know that I can connect with isql tool to my example database with

isql examples -u sysdba -p masterkey

or by using the full path

isql 'localhost:c:\db\examples.fdb' -u sysdba -p masterkey

And work from the Command Prompt.

But I'd like to use Base for the rest. How can I do that? Anybody knows?

I am not even sure If I should ask this here.
