Ubuntu 22.04 LTS下SSH登录尝试次数设置超过6次不生效的问题咨询

我目前在用Ubuntu 22.04 LTS系统，已经把sshd配置里的MaxAuthTries改成16了，但SSH登录的时候还是只让我尝试6次密码输入，哪怕把这个数值调得更高也没用。我已经重启过sshd服务，甚至好几次重启整个系统了，问题还是没解决，有没有大佬能告诉我怎么才能让它允许更多的登录尝试次数呀？

下面是我的sshd配置文件内容：

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.
