Mac OS behaves differently than other operating systems. It disregards the “service account” and performs the login call directly via the user account only. This is a rare combination of conditions that creates the issue, but it has happened.
The Itatem team does have a workaround for these conditions. If your users were somehow mis-configured, our support team can easily adjust on our system’s side to overcome this issue.
Please contact your Itatem representative or Itatem’s support directly at [email protected] and our team will get you back to business right away.
