[rt-users] MySql 'not allowed to connect to host...']

[Ron Alexander]

mysql.com/doc/en has pretty thorough docu for most problems. Just search 
on what you think, like 'user privileges'. You will be amazed!!
--------------------------------------
http://www.mysql.com/doc/en/Adding_users.html

You can add new users by issuing |GRANT| statements:

shell> mysql --user=root mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO monty at localhost
    ->     IDENTIFIED BY 'some_pass' WITH GRANT OPTION;
mysql> GRANT ALL PRIVILEGES ON *.* TO monty@"%"
    ->     IDENTIFIED BY 'some_pass' WITH GRANT OPTION;
mysql> GRANT RELOAD,PROCESS ON *.* TO admin at localhost;
mysql> GRANT USAGE ON *.* TO dummy at localhost;

These |GRANT| statements set up three new users:

|monty|
    A full superuser who can connect to the server from anywhere, but
    who must use a password |'some_pass'| to do so. Note that we must
    issue|GRANT| statements for both |monty at localhost| and|monty@"%"|.
    If we don't add the entry with |localhost|, the anonymous user entry
    for |localhost| that is created by|mysql_install_db| will take
    precedence when we connect from the local host, because it has a
    more specific |Host| field value and thus comes earlier in the
|user| table sort order. |admin|
    A user who can connect from |localhost| without a password and who
    is granted the |RELOAD| and |PROCESS| administrative privileges.
    This allows the user to execute the |mysqladmin reload|, |mysqladmin
    refresh|, and |mysqladmin flush-*| commands, as well as|mysqladmin
    processlist| . No database-related privileges are granted. (They can
be granted later by issuing additional |GRANT| statements.) |dummy|
    A user who can connect without a password, but only from the local
    host. The global privileges are all set to |'N'|—the |USAGE|
    privilege type allows you to create a user with no privileges. It is
assumed that you will grant database-specific privileges later.

You can also add the same user access information directly by issuing 
|INSERT| statements and then telling the server to reload the grant tables:
