in thread plugin 'mysql_old_password' cannot be loaded

Ok, looks like server has been upgraded from a pre 4.1 version.

Run this query to check if server is running with old_passwords=1

SELECT PASSWORD('anyword');

The result should be either

or

      That's good, if your password field in the user table is char(41) ( get DBA to run 'describe myslq.user' query ) then Scenario 3 at bottom of this document suggests that resetting the password will create a long password hash. That should be more compatible with the later MySQL libraries.

      Be AWARE of the effect on pre-4.1 clients though.
      In scenario 3, accounts with short hashes become inaccessible to pre-4.1 clients if you change their passwords without explicitly using OLD_PASSWORD().

        Thanks !

        I've found that this portable version of Strawberry include the version 4.033 of DBD::mysql, and the connection to the server works.

        Am I correct with saying that

        SET PASSWORD FOR 'some_user'@'some_host' = OLD_PASSWORD('password');

        • Will not change perl scripts (or other clients) that can connect now to keep on connecting ?
        • Will remove the error with the missing mysql_old_password plugin ?
