MySQL Error 4053: Unsupported IDENTIFIED BY Clause
Description
This error occurs when attempting to create or modify a MySQL user account using an `IDENTIFIED BY` clause (to set a password) with an authentication plugin that does not support direct password specification. It commonly arises when the chosen plugin expects password management to be handled externally or differently.
Error Message
IDENTIFIED BY clause during %s not supported for plugin %s.
Known Causes
3 known causesUsing `IDENTIFIED BY` with `auth_socket`
The `auth_socket` plugin authenticates users based on their operating system credentials and therefore does not use or support the `IDENTIFIED BY` clause for specifying a password.
External Authentication Plugin Conflict
Authentication plugins designed for external systems (e.g., LDAP, Kerberos, PAM) delegate password management, making the `IDENTIFIED BY` clause redundant or explicitly unsupported.
Misconfigured User Creation Syntax
The `CREATE USER` or `ALTER USER` statement includes an `IDENTIFIED BY` clause when the specified authentication plugin explicitly prohibits or ignores it, leading to a syntax conflict.
