I have a mongo server with ssl enabled. On this server I want to import data that is present on another server. So I want to mongodump and them mongorestore the data. Here is the mongodump command I ran

mongodump -h <host> -d <db> -u <user> -p <pass>.

I always see the following error
assertion: 18

{ code: 18, ok: 0.0, errmsg: "auth fails" }

I was able to run this command fine on other servers.
