Alexander,
so, why can a user do USE MYSQL when he has CREATE TEMPORARY TABLES?
Because of a MySQL bug...? I'm going to report this to MySQL.
My report: http://bugs.mysql.com/179 Let's see, what they'll say about it :-) Alexander M.

Well, after reading their answer, I guess we will have to rely on something else to set $is_superuser, like selecting records from mysql.user. Marc
Hi Marc & list, About the "CREATE TEMPORARY TABLES" privilege: I mixed something up here, it's completely independant from the CREATE privilege. The only advise I can give you is to revoke the global CREATE TEMPORARY TABLES privilege from all non-superusers and grant it to them on those databases they may access. -----Original Message----- From: Marc Delisle

We will have the same problem with users having a SHOW DATABASES privilege. Why not checking the current user's record in the user table, if we can access it? This should be the safest way.

Please avoid SHOW GRANTS. It's a little buggy in early 4.0 / 3.23 versions. And the big problem is that we have to know the correct Hostname as it appears in the user table. e.g. if user foo@192.168.0.% logs on from 192.168.0.26 we would intentionally build this query: SHOW GRANTS FOR foo@192.168.0.26; Unfortunally, this query would fail. The only way to determine a user's privileges properly is to use the `mysql` database. We should use the controluser for this purpose. Alexander M.

According to what you are checking now, the pma controluser is a superuser, isn't it? OK, your check is better than the old one, but it's not the perfect solution... Regards, Alexander M.

Yes, but the problem was that too many links were displayed on the main page for simple users. It's not a problem to display them for the admin who logs with the controluser. Anyway they don't work when clicked. Marc
