I am in the process of standardizing usernames at my company. All new people are [firstletterlastname], but there are several long time employees with usernames of just [lastname]. I am comfortable changing their username in Windows but we also rely heavily on a Power 7, which in turn is able to use windows credentials to connect on Windows machines to the emulator.
I know almost nothing about the Power 7. Is this even possible? My manager thinks that we would need to recreate all of their accounts and copy the permissions over. That seems like a horrible time punching through green screens to me.
