Well,
I hope the code is documented. You could simply paste the de-identified code here for public viewing.
Since you inherited this environment, you may need to close the cognitive gap (Centrify offers training or CBTs) and here are two documentation resources for you:
- If written on the UNIX/Linux side, most likely it was writen for adedit: Adedit guide
- If written on Windows in PowerShell, most likely it used the Centrify DirectManage PowerShell: Centrify PowerShell Guide
Alternatively, if you're a commercial customer with an existing contract, you should use the Customer Support options available to you.
If you are not, you should be at Centrify 5.3.x and up. The version you're running will sunset in Jan 2017 even for commercial customers with standard support.
