Dynamic Row Level Security using AD

[syasmin25]

Hello, 

I am trying to apply Dynamic Row Level security using the Active Directory. However, I am really new to the active directory. I have been searching to create hierarchy levels for each groups. I had followed the tutorial that I found here. I will be posting down the turorial link below. 
However, I was wanting to know, how do we create hierarchy levels for groups from there on? WHat I am trying to say is which columns should I be pulling in for the calculations?

how big is your AD?  That approach will only work for very small companies.  For larger companies you can use a RLS where you assign roles to AD groups manually.

It is around 15k rows. I did create AD groups. However, I am really new to RLS as well as Active Directory and do not know how to assign roles manually.
