Its attempting to ssh with the account you have specified as your management account either with imaging configurations or within your quickadd package. The account name would be listed under the computer record under the managed entry and will say "Managed by <account name>.

So when I encounter this, it's the rare situation where my management account credentials have some how gotten hosed. I end up changing management accounts (usually with a

sudo jamf enroll -prompt

and then once that is done, let JAMF delete the user with

jamf deleteAccount -username <management account username> -deleteHomeDirectory

After that, I'll re-enroll with my quick add package to get back to normal management. It's a PITA but it's about the cleanest way I've found to resolve that.

Thanks! I just added the account used to enroll it via a ARD and it worked! I'll create a script either in DeployStudio and/or in Jamf Pro for my other Macs and test, then deploy to the rest.
