My guess would be that administrators log onto the cluster using their personal/central accounts and then use sudo to issue administrative commands. This creates a log of who issued what commands at what time. Useful when you have more than one administrator and provides a level of tracking. Though personally I think using your "personal" everyday account for this is suboptimal. Best practice would suggest have a separate personal administrator account. So for example in a previous life my normal everyday account was njab14 no different than anyone else's account, but my I had a separate account administrator account was sjab14. That could do things like sudo had rights in the AD etc. etc. You can also do things like create groups of users that can log onto things that normal users cant. JAB. -- Jonathan A.
