[Zope] Help - Database Connection String

I have successfully installed Zope 1.10.3 , MySQL 3.21.31 and ZMySQLDA 1.1.3 on Linux Mandrake 5.2. Zope is working fine. However, when adding a ZMySQLDA database connector, I get an error message: - invalid connection string when I use mysql test as connection string. I tried several strings - still invalid. Can anyone help... Best regards...
