AD group doesn't have OU

AD group doesn't have OU-value in tbladgroups.

Also I see such information is collected into Exchange scanning tables

tblExchangeGroup

Hello there!

The database table tblADGroups stores the security groups Windows domain users and computers belong to, as scanned from the Active directory. There is no OU field in this database table, but are you perhaps referring to the Description or Name fields?

All objects in AD has distinguishedName, I think LS use it to generate OU-attribute .

I see it in tables

tblADComputers OU nvarchar
tblADusers OU nvarchar

but 

tblADGroups doesn't have OU

When I try to analyze tblADObjects and assigned users, computers, groups I have issue with placement of groups in AD.
