SSSD

After a few hours of debugging SSSD and mapping users/groups I wanted to make a post here to try and save someone the pain.

I had SSD configured correctly using the following document:

https://github.com/HortonworksUniversity/Security_Labs#lab-1

What I found by adding debug_level=7 to the sssd.conf file was this cryptic message:

Trying to resolve service 'AD_GC'

I realized at some point I was firewall'd off to the Active Directory Global Catalog port 3286, once I opened this I can now get the correct groups mapped to my SSSD users.

Hope this saves someone some time in the future!
