please help me with one hard task. I am not able to convince some admins and neither whole companies that installing & using SharePoint by using one (local) account method is against all best practices, against product information and in defiance of common sense. Even if I am using TechNet articles as references like this one or this one, blog articles and do the right installations for demo, I have no luck from many reasons. (Probably they need to hear it from someone more experienced than me or from huge amount of people. And no, I do not want to give up this fight). Often they do not see it as threat simply because they cannot think about consequences.
Can you please help me to build a list of consequences for such type of installations? Your experience what is impossible to use or do if you choose such kind of installation? For SP 2010 & SP 2013 as well.
