mongodb - Mongo 3.0.4 Unable to login -

i have create user in mongo 3.0.4 , enable authentication, can login in mac not in ubuntu 14.04

this how followed process enable authentication

use admin db.createuser(   {     user: "mongouser",     pwd: "user123#@!",     roles: [       { role: "read", db: "trackuser" },       { role: "readwrite", db: "trackuser" },       { role: "dbadmin", db: "trackuser" },       { role: "dbowner", db: "trackuser" }     ]   } ) 

auth=true in /etc/mongod.conf

$ mongo -u mongouser -p user123#@! --authenticationdatabase trackuser mongodb shell version: 3.0.4 connecting to: 127.0.0.1:27017/test 2015-07-16t14:44:54.741+0200 e query    error: 18 authentication failed.     @ db._authorthrow (src/mongo/shell/db.js:1266:32)     @ (auth):6:8     @ (auth):7:2 @ src/mongo/shell/db.js:1266 exception: login failed 

what in case?? same version working in mac not in ubuntu??

you can try adding new parameter db name this

-d trackuser 

right guess using

--authenticationdatabase trackuser
