If you open a shell for a collection which requires authentication you have to authenticate again in the shell. Use the following commands.

function// ()switch {to varcurrent statsdatabase = db.zipcode.stats(); var index = db.zipcode.getIndexes(); return { stats: stats, indexInformation: index }; } | ||||

The console mode only works if the server instance of Mongo has enabled server-side JavaScript. This is enabled by default.use my_database
// authenticate
db.auth('username', 'password') |
