Description:
http://dev.mysql.com/doc/refman/5.6/en/windows-authentication-plugin.html#windows-authenti...:

"To enable the plugin, start the server with the --plugin-load option. For example, put these lines in your my.ini file:

[mysqld]
plugin-load=authentication_windows.dll"

.. but there is no such file with a freshly installed MySQL 5.6.22 (using MySQL Installer) in C:\Program Files\MySQL\MySQL Server 5.6\lib where other plugin .dll's reside

How to repeat:
See above. I suppose that this may be a packaging issue with the MySQL Installer and it will be available from the .zip archive (but I have not checked yet) 

Suggested fix:
Include this plugin .dll with the MySQL Installer package. If a Windows Authentication Plugin is not relevant for a Windows Installer, where then?

Hi Peter,

Thanks for the bug report.  Just to be clear, are you observing this when using commercial-licensed MySQL Enterprise installer packages?  The Windows Authentication plugin is a commercial feature, and the plugin is not bundled with GPL-licensed community packages of MySQL.
[27 Jan 2015 16:21] Peter Laursen 
OK .. that explains! I use COMMUNITY.

Thanks for confirming, Peter.  I'll close this as "Not a Bug", since this is expected behavior and documented as a commercial-only feature at the top of the cited documentation.  If you feel this needs further clarification, please advise.

i have installed commercial edition still i cant find .dll in  /usr/lib64/mysql/plugin/, a quick response is highly appreciated.

You won't find Windows .DLLs - or the Windows Authentication Plugin in any form - in Linux packages of MySQL.  This is a Windows-only plugin, and part of Commercial packages only.

Todd,

Thanks for your response.

I am using MYSQL commercial version on redhat linux,when I add plugin-load=authentication_windows.dll in my.cnf file and restarted MySQL service and when I query show plugins it shows nothing.

And I tried below method and I got error saying authentication_windows.dll is not available in  /usr/lib64/mysql/plugin/ .

Please let me know if I am doing anything wrong.

Thank you,
Ashwin

I misunderstood your comment, I am able to connect mysql-linux using PAM.
