The issue does not exist when run as local user. The issue shows up when it is run as an AD user. In the function GetComputer, it tries authenticated AD bindings in order to search the computer's expanded CIMS object via our object helper class, specifically for the last password set attribute. The guid index database is part of the search and it is accessible only to root user. However both the root user and a AD user can obtain the authenticated bindings, but the AD user does not have the permission to read the index database stored locally in the cache.
These warning messages generated by adinfo do not impact command functionality in any way, therefore it is safe to ignore. The fix has been applied in Suite 2016 (CDC 5.3.0).
