I tried the GRANT syntax, but I too am having this problem. PLEASE HELP. This is frustrating. I am new to MySQL. Cannot connect as anything other than root, using shell or PHP pages on localhost. Here's my error: [in shell] ERROR 1045: Access denied for user: 'greg@localhost' (Using password: YES) [in php page] Warning: Access denied for user: 'greg@localhost' (Using password: YES) in /[...]/dbtest.php on line 14 (I'm developing under OS X 10.1, but that should not make a difference).
