I've never had an issue with changing a Management Account password in JAMF Pro 9.
Since we've moved to version 10, (10.4.1 to be exact) ¾ of my Macs are continually failing the policy:
Policy> Management Account > Change Account Password.
The only error I get is "Error: The Managed Account Password could not be changed.".
Any ideas would be great on how to resolve this.
