  I can change authentication on my MySQL server by using OLD_PASSWORD() sql
command and after that Generator can connect to mysql server (but still not
generates classes), but this won't resolve the main issue: ByteFx data
provider is dead (last version was realized 2004) and  does not support
MySQL 5.0 (and even 4.1), so  it's impossible to use it with stored
procedures, new data types and all other new features, which were created
since mysql version 3.
  When I made first post, I looked into the code and realized, that this is
not right forum for this question, because MonoDevelop uses sqlmetal for
generating dbml and sqlmetal uses DbLinq, which uses ByteFX. I hope, that I
will be able to recompile DbLinq with MySQL connector (will try it further)
and will check this issue again.
