We have a Yosemite machine where the primary user has recently married and is requesting us to change her name in all of our systems. Given the quasi-delicate relationship between Apple and Active Directory I am hesitant to just start changing / updating her information in AD and corrupting her profile on her Apple.
The machine is joined to AD, the user logs into her AD account and everything is working fine.
FirstName, Last Name, Display Name -- I would think these AD fields can be changed without any impacts to her computer. Possibly I need to manually change these in the native Mail.app on her machine but that is OK.
I assume I can also change her primary Exchange alias.
User Logon Name (UPN) and pre-Windows 2000 logon name -- I'm hesitant here --- if this were a windows user I would change them no problem and things end up being fine since the SID does not change; but can I do that with Apple? On cursory inspection only, it looks like Apple is going more off of user name than the unique identifier so I'm thinking changing these would be problematic. Is this a correct assumption?
