Description

Error 1410, 'You are not allowed to create a user with GRANT', occurs when you attempt to combine the user creation process with privilege assignment, specifically the `WITH GRANT OPTION`, within a single `CREATE USER` statement. MySQL's security model dictates that user creation and privilege granting are separate operations.

Error Message

You are not allowed to create a user with GRANT

Known Causes

2 known causes

⚠️

Incorrect CREATE USER Syntax

You are attempting to use `WITH GRANT OPTION` directly within a `CREATE USER` statement, which is syntactically disallowed by MySQL.

⚠️

Misunderstanding Privilege Workflow

MySQL requires user accounts to be created first, and then privileges, including `GRANT OPTION`, are assigned in subsequent, separate `GRANT` statements.

Solutions

3 solutions available

1. Grant Necessary Privileges to the Current User easy

The user attempting to create a new user with GRANT privileges lacks the required permissions. Grant them the `CREATE USER` and `GRANT OPTION` privileges.

1

Log in to your MySQL server as a user with administrative privileges (e.g., 'root').

2

Execute the following SQL command to grant the necessary privileges to the user who is encountering the error. Replace 'your_user'@'your_host' with the actual username and host of the user experiencing the error.

GRANT CREATE USER, GRANT OPTION ON *.* TO 'your_user'@'your_host';
FLUSH PRIVILEGES;

3

Now, the user 'your_user'@'your_host' should be able to create new users with GRANT privileges.

2. Use an Administrative User for User Creation easy

Instead of trying to grant permissions to a non-administrative user, use a user account that already possesses the necessary privileges.

1

Identify a MySQL user account that has the `CREATE USER` and `GRANT OPTION` privileges. This is typically the 'root' user or another administrative account.

2

Log in to your MySQL server using this administrative account.

3

Execute the `CREATE USER` and `GRANT` statements using this administrative account. For example, to create a new user 'new_user' with password 'secure_password' and grant them privileges on a specific database 'my_database':

CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'secure_password';
GRANT SELECT, INSERT, UPDATE, DELETE ON my_database.* TO 'new_user'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

3. Review and Adjust User Privileges Systematically medium

This is a more thorough approach to ensure proper privilege management and avoid future issues by understanding and re-evaluating existing user permissions.

1

Connect to your MySQL server with administrative privileges.

2

Inspect the privileges of the user who is encountering the error. Replace 'problem_user'@'problem_host' with the actual user's credentials.

SHOW GRANTS FOR 'problem_user'@'problem_host';

3

Analyze the output of `SHOW GRANTS`. If the user does not have `CREATE USER` and `GRANT OPTION`, you will need to grant them (as per Solution 1) or use an administrative user (as per Solution 2).

4

If you intend for this user to manage other users' permissions, ensure they have the `CREATE USER` and `GRANT OPTION` privileges. If their role is more limited, consider revoking unnecessary privileges and granting only what's required.

REVOKE ALL PRIVILEGES ON *.* FROM 'problem_user'@'problem_host';
GRANT SELECT ON my_database.* TO 'problem_user'@'problem_host'; -- Example: Granting specific read access

5

After making any privilege adjustments, always run `FLUSH PRIVILEGES` to reload the grant tables.

FLUSH PRIVILEGES;
