Problem with Additional Record in database.yml

Hi all,
I try to set up an additional database. Therefore, I followed the steps
described in
http://wiki.rubyonrails.org/rails/pages/HowtoUseMultipleDatabasesWithFixtures.
But i got a in “`establish_connection’: legacy_test database is not
configured (ActiveRecord::AdapterNotSpecified)” message.
My database.yml looks fine but I still get this message. Does anyone
know how to fix this problem?

Regards,
