Greetings everyone,
This is my first time posting here, so I hope this is the right place. I've created a function/script that can be used for setting up SSL on Odata on NAV2015/2017. This script also accounts for the bug in setting up the Odata SSL by turning it off and back on again after setting up the certificate. This isn't a full documentation on how to import the cert (so you'll still need to have imported the cert).
Anyways, here is the github
