* detection
*
* @todo fix to get really all privileges, not only explicitly defined for this user
* from MySQL manual: (http://dev.mysql.com/doc/refman/5.0/en/show-grants.html)
* SHOW GRANTS displays only the privileges granted explicitly to the named
* account. Other privileges might be available to the account, but they are not
* displayed. For example, if an anonymous account exists, the named account
* might be able to use its privileges, but SHOW GRANTS will not display them.
