# ABOUT THIS PROGRAM
#
# NAME
#   enableARD.sh -- Enable ARD and Configure Remote Management Settings
#
# SYNOPSIS
#   sudo enableARD.sh
#   sudo enableARD.sh <mountPoint> <computerName> <currentUsername> <targetUsername>
#
#   If the $targetUsername parameter is specified (parameter 4), this is the account that will be 
#   granted access to ARD.
#
#   If no parameter is specified for parameter 4, the hardcoded value in the script will be used.
#
# DESCRIPTION
#   This script enables and configures remote management settings for a user.  There are a number
#   of options that the script is capable of configuring, which should be specified in the privs
#   string.  Please see the kickstart man page for more information.
#
#   The following options are available in the kickstart application:
#
#       -DeleteFiles
#       -ControlObserve
#       -TextMessages
#       -ShowObserve
#       -OpenQuitApps
#       -GenerateReports
#       -RestartShutDown
#       -SendFiles
#       -ChangeSettings
#       -ObserveOnly
#       -mask
#
#   ARD access is granted and priviliges  are assigned to an individual account on computers running 
#   Mac OS X 10.3 and later. It can be used with a hardcoded value in the script, or read in as a 
#   parameter.  Since the Casper Suite defines the first three parameters as (1) Mount Point, 
#   (2) Computer Name and (3) username, we are using the forth parameter ($4) as the passable 
#   parameter.  We do not use $3 since it may not match up to the username that we want to grant
#   access for.

I found using kickstart to setup ARD doesn't allow you to configure it so that the curtain function works. Anyone else find that and know of a workaround?

To make that work it’s important to distinguish where you seek to configure the functionality you wish to use.

The kickstart command does a great job in our environment to get a remote Mac configured and authorized with the right logins.

If you are wishing to configure the admin application properly simply configure the setting you want in the GUI, capture the resulting .plist, strip the .plist down to only what you wish to force, then build a custom .mobileconfig file (user domain) and scope it out or if you just want to set it up initially, deploy the .plist to your users.

Need a little help with this script. I have edited the username per this line

HARDCODED VALUE FOR "USERNAME" IS SET HERE

targetUsername="admin-user"

The script keeps failing. Am I missing something ?? Should I be editing something else as well ?

Here is the error from Jamf

Any resolution to this issue?
