macos 10.14 jamfpro could not reset password

The Jamf binary uses dscl to reset passwords, and there's been quirks with that method since High Sierra introduced secureToken. I would create a policy that uses sysadminctl to change the password. It force creates a new Keychain, as well.

sudo sysadminctl -adminUser AdminUserHere -adminPassword AdminPasswordHere -resetPasswordFor UserToBeResetHere -newPassword NewPasswordHere
