GRANT is meant for adding privileges to users. Confusingly, it also has the ability to create users and change their passwords. This functionality is deprecated and should not be used. If you use GRANT with IDENTIFIED you can change the user’s password: When IDENTIFIED is present and you have the global grant privilege (GRANT OPTION), … Read more
In general, a non-administrator user has this access to the registry: Read/Write to: HKEY_CURRENT_USER Read Only: HKEY_LOCAL_MACHINE HKEY_CLASSES_ROOT (which is just a link to HKEY_LOCAL_MACHINE\Software\Classes) It is possible to change some of these permissions on a key-by-key basis, but it’s extremely rare. You should not have to worry about that. For your purposes, your application … Read more
When you log on Windows creates an access token. This identifies you, the groups you are a member of and your privileges. And note that whether a user is an administrator or not is determined by whether the user is a member of the Administrators group. Without UAC, when you run a program it gets … Read more
The USAGE-privilege in mysql simply means that there are no privileges for the user ‘phpadmin’@’localhost’ defined on global level *.*. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*. So if you want to remove all the privileges and start totally from scratch do the following: Revoke all privileges on database level: REVOKE ALL … Read more

Stop the MySQL service through Administrator tools, Services. Modify the my.ini configuration file (assuming default paths) C:\Program Files\MySQL\MySQL Server 5.5\my.ini or … Read more

You could query the table_privileges table in the information schema: SELECT table_catalog, table_schema, table_name, privilege_type FROM information_schema.table_privileges WHERE grantee=”MY_USER”
I don’t believe that it is possible to elevate the currently running process. It is built into Windows Vista that administrator privileges are given to a process upon startup, as I understand. If you look at various programs that utilise UAC, you should see that they actually launch a separate process each time an administrative … Read more
os.geteuid gets the effective user id, which is exactly what you want, so I can’t think of any better way to perform such a check. The one bit that’s uncertain is that “root-like’ in the title: your code checks for exactly root, no “like” about it, and indeed I wouldn’t know what “root-like but not … Read more
