Re: "mysql_connect(): Client does not support .... ANSWER"

Below is quoted directly from the MySQL.net manual located at:

http://dev.mysql.com/doc/mysql/en/old-client.html


---------------------------------
To solve this problem, you should use one of the following approaches:

Upgrade all client programs to use a 4.1.1 or newer client library.

When connecting to the server with a pre-4.1 client program, use an account that still has a pre-4.1-style password.

Reset the password to pre-4.1 style for each user that needs to use a pre-4.1 client program. This can be done using the SET PASSWORD statement and the OLD_PASSWORD() function:

mysql> SET PASSWORD FOR
-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

Alternatively, use UPDATE and FLUSH PRIVILEGES:

mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
-> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES;

Substitute the password you want to use for ``newpwd'' in the preceding examples. MySQL cannot tell you what the original password was, so you'll need to pick a new one.

Tell the server to use the older password hashing algorithm:

Start mysqld with the --old-passwords option.

Assign an old-format password to each account that has had its password updated to the longer 4.1 format. You can identify these accounts with the following query:

mysql> SELECT Host, User, Password FROM mysql.user
-> WHERE LENGTH(Password) > 16;

For each account record displayed by the query, use the Host and User values and assign a password using the OLD_PASSWORD() function and either SET PASSWORD or UPDATE, as described earlier.

For additional background on password hashing and authentication, see Section 5.5.9, “Password Hashing in MySQL 4.1”.
----------------------

Note: I used the UPDATE/FLUSH proceedure above and everything works fine now.
