You are trying to connect to a 4.1 server with a 4.0 client. This is
explained in the manual <http://dev.mysql.com/doc/mysql/en/old-client.html>.

I am confused as to why I am unable to connect to my MySQL DB 4.1.13 via
DBI:DBD in PERL.
This is on SuSE Pro 9.1, perl-5.8.3-32, perl-DBI-1.41-28,
perl-DBD-mysql-2.9003-22.
I am getting the following error:
DBI connect('host=localhost;database=lts','dbmgr',...) failed: Client does not
support authentication protocol requested by server; consider upgrading MySQL
client at ./lts_connect_test.pl line 25
Can't call method "disconnect" on an undefined value at ./lts_connect_test.pl
line 30.
I have just created the user and granted all privileges with the following
sequence:
mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 7 to server version: 4.1.13-Max
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> GRANT ALL PRIVILEGES ON lts.* TO 'dbmgr'@'localhost' IDENTIFIED BY
'pwd';
Then I run the following code:
---------------------------------
#!/usr/bin/perl -w
use DBI;
use strict;
my $lts_username='dbmgr';
my $lts_password='pwd';
my $lts_data_source;
my $lts_dbh;
connect_lts();
disconnect_lts();
sub connect_lts {
my $lts_source='DBI:mysql:host=localhost;database=lts';
$lts_dbh = DBI->connect($lts_source,$lts_username,$lts_password);
}
sub disconnect_lts {
$lts_dbh->disconnect();
}
---------------------------------
And get the error listed above. I have also created a user that has only
SELECT privilege and it works fine with this slight modification to the above
code:
my $lts_username='wmdbread';
my $lts_password='';
I have also run FLUSH PRIVILEGES; in mysql as root and it did not change
anything. I have also verified that the mysql.db table shows the users with
the proper db and privileges.
Has anyone experienced this? Any ideas?
Thanks,
Darrell Cormier
