MySQL 5.5 Pam Authentication
Posted:

I have the pam_authentication plugin installed on a MySQL 5.5.19 server. I log in without issue from the command line and also from MySQL Workbench. When trying to log in with Toad for MySQL 6.0.1.1723 I get the following error.
MySQL Database Error: Client does not support authentication protocol requested by server; consider upgrading MySQL client
I also tried connecting with an SSH connection and using the MySQL libraries. In that case I get the following error.
Devart.Data.MySql.ClientLibraryLoadException
Unable to load libmysql.dll.
Stack Trace:

Is there a workaround to get this working?
Thank you,
Jeremy

I solved this problem by downloading the 32bit version of MySQL 5.5.19 for Windows and copying the libMySQL.dll to the Toad installation directory. I then added this path to my user PATH environment variable. In my case it was located at C:\Program Files (x86)\Quest Software\Toad for MySQL Freeware 6.0.
As with the previous post I still needed to use an SSH connection and check Use MySQL libraries.
