How to create root user

```
db.createUser({user: 'sa', pwd:'Serg1990SA', roles: ['root']})
Successfully added user: { "user" : "sa", "roles" : [ "root" ] }
```

Admin user
```
use admin
db.createUser(
  {
    user: "siteUserAdmin",
    pwd: "password",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)
```

MongoDB 3.0
If you can't connect to db with auth parameters:

The new auth schema were introduced with Mongo 3 SCRAM-SHA-1 
and not all GUI tools are support it (for now only MongoChef),
The workaround is to force mongo use old (MongoDB-CR) auth schema and then recreate users

you can check that user has new auth schema by:
```
db.system.users.find({user: 'serg'}).pretty()
```

```
mongo
use admin
db.system.users.remove({})    <== removing all users
db.system.version.remove({}) <== removing current version 
db.system.version.insert({ "_id" : "authSchema", "currentVersion" : 3 })
```
