mysql未开启ssl模块_MySQL：未在授权中显示SSL

MySQL 8在SHOW GRANTS输出中未显示REQUIRE SSL.

在MariaDB上,当我使用REQUIRE SSL创建用户时,授权中将显示该用户：

Server version: 10.2.22-MariaDB MariaDB Server

MariaDB [(none)]> drop user if exists 'test';

MariaDB [(none)]> create user 'test' REQUIRE SSL;

Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> show grants for 'test';

+----------------------------------------------+

| Grants for test@% |

+----------------------------------------------+

| GRANT USAGE ON *.* TO 'test'@'%' REQUIRE SSL |

+----------------------------------------------+

但是在MySQL8中,我看不到需要SSL：

mysql> drop user if exists 'testu';

mysql> create user 'testu' REQUIRE SSL;

mysql> show grants for 'test';

+----------------------------------+

| Grants for test@% |

+----------------------------------+

| GRANT USAGE ON *.* TO `test`@`%` |

+----------------------------------+

尝试不使用SSL进行连接确实会产生错误,但是如果未在授权中显示该信息,我如何查看启用了该功能的用户呢？
