1.尝试在命令行下删除:
[IPS-luser-manage-aaa]dis th
#
local-user aaa class manage
password hash $h$6$yKjUmjMjwBzdIsfN$vt6wet776aQ+0MGaKWyDNsHvqdwHFM6dilH6iHOhnRMpjfNGykOIN9zDJy3q5+12Y2aYp3D1Q8YoCYmx5Zw6Jg==
authorization-attribute user-role security-audit
#
return
[IPS-luser-manage-aaa]qu
[IPS]undo local-user aaa c m
The local user being the only security auditor cannot be removed.
[IPS]
2.尝试在web下删除,还是不行:

3.翻译一下这句话
he local user being the only security auditor cannot be removed .
无法删除作为唯一安全审计员的本地用户。
4.尝试给这个账户更改权限,还是失败!
[IPS-luser-manage-aaa]authorization-attribute user-role network-admin
This operation will delete security auditor role of the user. Are you sure? [Y/N]:y
Cannot cancel the security auditor role of a user who is the only security auditor in the system.
又翻译一下:该操作将删除该用户的“安全审计员”角色。你确定吗?[Y / N]: Y
不能取消系统中唯一的安全审计员角色。
5.总结
这个权限用户创建后就没办法删除了,必须本地存在一个这个权限的用户,新增一个这个账户来代替他,再试着去删除它就可以了。
