IdentityNow Rule Guide - After Modify Rule

7 Kudos

Purpose

This rule is used to execute PowerShell commands on the IQService component after a source account is modified, enabled, disabled, or unlocked.

Execution

Connector Execution - This rule executes within the Virtual Appliance and may offer special abilities to perform connector-related functions, and may offer managed connections to sources.
Logging - Logging statements are viewable within the ccg.log on the Virtual Appliance and by SailPoint personnel.

Input

Argument	Type	Purpose
Application	System.Collections.Hashtable	Map of the application configuration.
Request	SailPoint.Utils.objects.AccountRequest	A reference to the account request provisioning instructions.
Result	SailPoint.Utils.objects.ServiceResult	A reference to the provisioning result that can be manipulated if needed.

Architecture Best Practices

For supportability, it is recommended that the After Creation rule be written with only the most basic logic necessary to trigger a PowerShell script, and shift the bulk of the downstream events and/or modifications to the PowerShell script itself. This script would reside on the client's servers and could therefore be easily maintained or modified by the client as needed. It also allows the client to implement changes to the PowerShell scripted functionality without requiring code review by SailPoint, as the code runs outside of the IdentityNow platform.

		<Description>
			This is an IQService afterScript - On a successful provisioning event, this after script should be used as the starting point for 
            initiating a separate PowerShell script residing on the client's IQService server.

            Configuration tasks include:
             - Set a proper location for the $logFile variable
             - Set the proper script location and name for the $command variable
             - Set the $enableDebug flag to $true or $false to toggle debug mode

# SETUP
# Instructions (for each IQService host that could run the script):
#   - Update the path to Utils.dll (can be an unqualified path like "Utils.dll" since script is copied to IQService folder for execution)
#   - Make sure Utils.dll is in the specified folder on each IQService host
#   - Be sure the account that runs IQService has appropriate permissions to create directories and set permissions on them
#   - Be sure to set the "run as" account for the IQService in Windows Service to the above-specified account instead of just the "logged on" user
#   - Set a proper location for the $logFile variable
#   - Set the $enableDebug flag to $true or $false to toggle debug mode
