Description

This fixlet gives admin rights to a local user. After 30 minutes, a file is touched on the system to trigger a fixlet to remove admin rights. To allow users to elevate admin rights as needed, action this task against an automatic group. There is no end date on the task and it will be reapplicable and re-offered while the action is open.

To remove admin rights after 30 minutes, you must run the "System Configuration: Remove Temporary Admin Rights - macOS"

The status of the admin rights are reported through the analysis "Temporary Admin Privliges Report - macOS".

#
# This script was modified from Andrina Kelly's version presented at JNUC2013 for allowing
# a user to elevate their privelages to administrator once per day for 30 minutes. After
# the 30 minutes if a user created a new admin account that account will have admin rights
# also revoked. If the user changed the organization admin account password, that will also
# be reset.
#
# To accomplish this the following will be performed:
#            - A launch daemon will be put in place in order to remove admin rights
#            - Log will be written to tempAdmin.log
#            - This policy in Jamf will be set to only be allowed once per day
#
# REQUIREMENTS:
#            - Jamf Pro
#            - Policy for enabling tempAdmin via Self Service
#            - Policy to remove tempAdmin via custom trigger
#            - tempAdmin.sh & removeTempAdmin.sh Scripts
# - orgAdmin encrypted password specified in Jamf Pro parameter #4
