MySQL Error 3925: Anonymous User for PRIVILEGE_CHECKS_USER
Description
This error indicates that the `PRIVILEGE_CHECKS_USER` setting for a MySQL replication channel has been configured with an anonymous user (`''@''`). MySQL explicitly disallows anonymous users for this security-sensitive parameter, preventing the replication channel from being established or operating correctly.
Error Message
PRIVILEGE_CHECKS_USER for replication channel '%s' was set to ``@`%s`, but anonymous users are disallowed for PRIVILEGE_CHECKS_USER.
Known Causes
3 known causesExplicit Anonymous User Configuration
The `PRIVILEGE_CHECKS_USER` parameter for a replication channel was directly set to an anonymous user (`''@''`), which MySQL security policies prohibit.
Configuration Script Error
An automated script or deployment process inadvertently configured `PRIVILEGE_CHECKS_USER` with an anonymous user, leading to a disallowed state.
Incomplete User Specification
A user definition for `PRIVILEGE_CHECKS_USER` was incomplete or malformed, causing MySQL to interpret it as an anonymous user.
