Unable to login with credentials used to create mongo user

[hugo lassiege]

Hi,

I've open an issue on Github (https://github.com/ansible/ansible/issues/7157) about mongo_user module. 

I'm trying to use mongo_user to create some users. However, I'm unable to login with the credentials specified.

I use the following commands :

- name: add Mongo admin

  mongodb_user: database=admin name=bigadmin password=BigBosS roles='root' state=present

  sudo: true         

and then, if I try to connect, it fails : 

mongo admin -u bigadmin -p BigBosS

=> auth failed

But if I add this user manually on mongo it works 

db.addUser({user: "superadmin", pwd: "BigBosS", roles: [{role:"root", db:"admin"}]})

mongo admin -u superadmin-p BigBosS

=> auth successfull

The weird thing is that the password is different in the admin db.system.users collection :

>  db.system.users.find()

{ "_id" : "admin.bigadmin", "user" : "bigadmin", "db" : "admin", "credentials" : {  "MONGODB-CR" : "8757ec7d8b6d462f69e10c51d36ff9c1" }, "roles" : [ { "role" :  "root", "db" : "admin" } ] }

{ "_id" : "admin.superadmin", "user" : "superadmin", "db" : "admin", "credentials" : {  "MONGODB-CR" : "96dfab41377d3965ce104f7b1f3d8044" }, "roles" : [ { "role" :  "root", "db" : "admin" } ] }

I think the password shoud be identical.

Any idea about that ?
