MongoDB AuthenticationFailed with MONGODB-CR mechanism
I created these two users in my admin database:
db.auth('admin','password')
1
> db.getUsers()
[
{
"_id" : "admin.siteUserAdmin",
"user" : "siteUserAdmin",
"db" : "admin",
"roles" : [
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
},
{
"_id" : "admin.admin",
"user" : "admin",
"db" : "admin",
"roles" : [
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
}
]
I am correctly authenticated from my localhost, but when I try to use an external client to connect to my database, I got this error:
Failed to authenticate admin@admin with mechanism MONGODB-CR: AuthenticationFailed MONGODB-CR credentials missing in the user document
How to fix it?

As stated here : MongoDB 3 authentication mechanism was changed from MongoDB Challenge and Response (MONGODB-CR) to challenge and response mechanism (SCRAM-SHA-1) .
You need to delete the created user and then change admin.system.version.authSchema to 3 instead of 5 . Then recreating your user should solve the problem:
var schema = db.system.version.findOne({"_id" : "authSchema"})
schema.currentVersion = 3
db.system.version.save(schema)

My symptom is different from the above question, but I am writing here for reference.
I am getting an on-premises authentication error.
This happens for me when I use a match match between a server and a mongodb client.
For example:
- Server: mongod version v3.4.2.
- Client: mongo version is 2.6.10.
When I access the server using mongo with a valid user and password, it crashes due to a version mismatch.
