SERVER-88594 is the main test for the authorization test for internal commands. It provides the test setups and tests for authorization success (with credential) and failure (without appropriate credential). 

A successful authorization test should include 1) access success with proper credentials 2) access failure without proper credentials.

The following four commands are currently running without proper credential (the expected behavior was failure, observed behavior was that the command ran successfully). This ticket investigates the reasons and takes appropriate actions.
