A.2.3 Client does not support authentication protocol

MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that

used by older clients. If you upgrade the server to 4.1, attempts to connect to it with an older client may fail with the following

message:

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.

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.
