NICE but not working:

site-mysql/init.pp
class site-mysql inherits mysql {
    # operations user
    mysql_user{'operations@10.2.111.%':
        password_hash => "*DEE65258DA0F2513DE84AD4C1E15557C65602548"
    }
    mysql_grant{'operations@10.2.111.%':
        privileges => 'all',
        require => [ Mysql_user['operations@10.2.111.%'] ],
    }
}

site-mysql/kyushu.pp
class site-mysql::kyushu inherits site-mysql {
    $mysql_rootpw = 'eu7shae2ahf5theibohS9ri5'

    mysql_user{'mgroner@10.2.111.%':
        password_hash => "*3ADE0F8B147F85334D5444D01C04918AC6A1B4B0",
    }
    mysql_grant{'mgroner@10.2.111.%':
        privileges => 'all',
        require => [ Mysql_user['mgroner@10.2.111.%'] ],
    }
    mysql::default_database{
        'pitc_swissflirt_test':
            username => 'pitc_swissflirt',
            password => '*65B3F53CF360764B6B8851FEF58D66DFAE22E809';
    }
}


working alternative:
site-mysql/init.pp
class site-mysql {
    # empty
}

class site-mysql::kyushu {
    $mysql_rootpw = 'eu7shae2ahf5theibohS9ri5'
    include mysql
    include mysql::default_user

    mysql_user{'mgroner@10.2.111.%':
        password_hash => "*3ADE0F8B147F85334D5444D01C04918AC6A1B4B0",
    }
    mysql_grant{'mgroner@10.2.111.%':
        privileges => 'all',
        require => [ Mysql_user['mgroner@10.2.111.%'] ],
    }
    mysql::default_database{
        'pitc_swissflirt_test':
            username => 'pitc_swissflirt',
            password => '*65B3F53CF360764B6B8851FEF58D66DFAE22E809';
    }
}

_why not that way:

site-mysql/init.pp
class site-mysql inherits mysql {
    # operations user
    mysql_user{'operations@10.2.111.%':
        password_hash => "*DEE65258DA0F2513DE84AD4C1E15557C65602548"
    }
    mysql_grant{'operations@10.2.111.%':
        privileges => 'all',
        require => [ Mysql_user['operations@10.2.111.%'] ],
    }
}

site-mysql/kyushu.pp
class site-mysql::kyushu {
    $mysql_rootpw = 'eu7shae2ahf5theibohS9ri5'
    include site-mysql

    mysql_user{'mgroner@10.2.111.%':
        password_hash => "*3ADE0F8B147F85334D5444D01C04918AC6A1B4B0",
    }
    mysql_grant{'mgroner@10.2.111.%':
        privileges => 'all',
        require => [ Mysql_user['mgroner@10.2.111.%'] ],
    }
    mysql::default_database{
        'pitc_swissflirt_test':
            username => 'pitc_swissflirt',
            password => '*65B3F53CF360764B6B8851FEF58D66DFAE22E809';
    }
}
