Hi:

I tried to setup my mongoDB cluster in authentication mode. Was able to create a admin user with role "userAdminAnyDatabase" in "admin" db in not authentication mode. Once I turn on the authentication mode, any operation I perform, I get the following error for any action as the "admin" user.

{"error":"error creating initial database config information :: caused by :: can't find a shard to put new db on"}

.

Here is the complete procedure that we followed. Version of mongodb being used is 2.6.4.
