用户反馈说没有权限，报错如下：
not authorized on testdb to execute command { find: "Schedule", filter: {}, skip: 0, limit: 20, maxTimeMS: 60000, lsid: { id: UUID("41a5218c-071f-41c4-9b06-a28fb60f8015") }, $db: "testdb" }
查看用户的权限
> db.getUser('test_user')
{
"_id" : "admin.test_user",
"userId" : UUID("c041ed33-2dba-477c-8bb3-091955937f66"),
"user" : "test_user",
"db" : "admin",
"roles" : [
{
"role" : "dbAdminAnyDatabase",
"db" : "admin"
}
],
"mechanisms" : [

"SCRAM-SHA-256"
]
}

角色dbAdminAnyDatabase与dbAdmin含有相同的权限，除了local和config库。从5.0开始，还包含了applyOps的权限。
查看一下该角色都有哪些特权：

授权

再次查看用户的权限
