In 5.6, this requires an update of er, and FLUSH PRIVILEGES: UPDATE er TO you need to update the mapping for the anonymous user. You can create the additional user account: CREATE USER LOCK TO PROXY ON PROXY ON you want to add another group of users with different privileges. As an example, let’s say you are using the PAM authentication plugin, and you’ve created accounts as follows to support this: CREATE USER WITH authentication_pam

Updating proxy user mappingĪnother use case which required direct updates of the er table in the past is modification of the proxy user mapping for authentication plugins like PAM or Windows Native authentication. Mysql> ALTER USER IDENTIFIED WITH sha256_passwordįor users who have deployed the mysql_no_login plugin to lock down system accounts, that also means you can convert to the new “locked account” introduced in MySQL Server 5.7.7, without affecting users or directly modifying er. The new ALTER USER syntax supports this use case: mysql> CREATE USER IDENTIFIED WITH mysql_native_password In earlier versions, there was no way to change the authentication plugin for an existing user account without directly manipulating the er table (discouraged). Here’s a couple of important use cases the new syntax covers: Changing authentication plugin These attributes, and the syntax by which they are modified, is now consistent across CREATE USER and ALTER USER commands. Password/credentials or auth plugin mapping.These are consistent with CREATE USER – the same attributes which can be defined with a CREATE USER command can now be modified using an ALTER USER command. This all changes for the better in MySQL Server 5.7 – here’s how: Account attributes MySQL has a long history of confusing these – for example, requiring a GRANT command to set account resource limits or require SSL. With changes made in MySQL Server 5.7.6, a better distinction is made between privilege-level attributes (those which are managed via GRANT and REVOKE statements) and account-level attributes (those managed using CREATE USER and ALTER USER statements). Before MySQL Server 5.7.6, ALTER USER could only be used to expire a user’s password. You can either allow all three or restrict all three fro this user's access to the kumar database.Complimenting the expanded CREATE USER syntax introduced in MySQL Server 5.7.6 is more useful ALTER USER syntax. | GRANT ALL PRIVILEGES ON `kumar`.* TO |ĮRROR 1044 (42000): Access denied for user to database 'kumar2' I tried to drop kumar2 mysql> show grants for Grants for |

Something to keep in mind: The DROP privilege encompasses databases, table, and views. Perhaps you want to remove the DROP privilege at the global user level UPDATE er SET drop_priv = 'N' WHERE user='.' AND host='.' and db='.'
