The problem is in the MySQL version.

Version 4.1 uses a different password hash length than previous version of MySQL

see details at

http://www.mysql.com/doc/en/Password_hashing.html

The only solution I found is to use the default log in. No user name and no password. Or change to an earlier version of MySQL.
