ARS v8.2.1 SP6 does not accept "Controlled Groups" type objects as members of a Dynamic Group. Previous ARS v8.2.1 SPs as well as previous ARS versions do accept this type of Groups as members using rule type "Include by Query"
Note that rule "Include Explicitly" works
Steps to reproduce the issue:
1.- Create a new DG
2.- Use "Include by Query" rule
3.- Select find Groups
4.- Access the "Group Type" tab and select "Controlled Group"
Note: if you add a rule via the "Advanced" tab to find those Controlled Groups using a specific attribute does not work either.
