MySQL behaves like this: Usernames, passwords, and database and table names are case sensitive in grant table entries. Hostnames and column names are not. > >The fact that you observed this using the "magic" hostname >"localhost" may indicate that MySQL is "cheating" by doing its own >management of this unique name.

On UNIX, it means "connect using the UNIX domain socket rather than TCP/IP". So in this case, DNS is not involved. In any case, I do not observe a difference between setting up user accounts using host 'localhost' versus 'LOCALHOST'. I *do* observe case sensitive hostname behavior for SHOW GRANTS. This should not be.
