Since upgrading to 9.72, we have a seen a steady trickle of Macs falling into an 'unmanaged' state. The machines still check in, and have the updated binary, but they show as unmanaged. They seem to fall into two groups:
Enforcing management or running sudo jamf manage often yields 'Device Signature Error - A valid device signature is required to perform the action'.
Some machines re-enrolling works, others we get the Device Signature Error.
Anyone else seeing similar things after moving to 9.72?
I ran into this issue as well. I even posted it here: https://jamfnation.jamfsoftware.com/discussion.html?id=14406
I ended up having to generate a new Tomcat cert inside the JSS Interface and re-uploading our SSL Certificate.
@usher.br our issue seems to be a little different as we only saw a small percentage become unmanaged (less than 5%), and it happened at the time of our upgrade to 9.72. So far, the only fix has been to delete the computer from the JSS, then re-enroll the machine.
That being said, I generated new Tomcat SSL certificates on our JSS webapps, and even though they weren't expired yet, we are now seeing much better performance in terms of getting inventory from machines (before it would sit on submitting data to jss for minutes, now it is very quick). So thanks for that, it looks like we may have had an issue with the keystore as well.
I'm not convinced yet that the unmanaged machines are related to the SSL certs but maybe they are, hard to say. thanks again for the suggestion.
