MySQL Bugs: #116616: Documentation around AUTHENTICATION_CLIENT

Bug #116616	Documentation around AUTHENTICATION_CLIENT_PLUGINS in MySQL 9.0 is misleading
Submitted:	11 Nov 2024 15:37	Modified:	11 Nov 2024 16:28

Version:	9.0	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
The release notes for MySQL 9.0 read:

"The mysql_native_password authentication plugin, deprecated in MySQL 8.0, has been removed, and the server now rejects mysql_native authentication requests from older client programs which do not have CLIENT_PLUGIN_AUTH capability. For backward compatibility, mysql_native_password remains available on the client; the client-side built-in authentication plugin has been converted into a dynamically loadable plugin."

https://dev.mysql.com/doc/relnotes/mysql/9.0/en/news-9-0-0.html

However, the default build instructions leave `-DWITH_AUTHENTICATION_CLIENT_PLUGINS` unset, and that plugin is not built.

How to repeat:
Build MySQL 9.0

Inspect that the authentication client plugins are not compiled

Suggested fix:
Add `-DWITH_AUTHENTICATION_CLIENT_PLUGINS=yes` to the default build args.
