nested ldap groups with openldap

Hi

if I select " Fetch Nested Group" do the F5 extend the search with 

memberof:1.2.840.113556.1.4.1941

or does it grab MemberOf info and div into it further ?

so 

dn: mail=alex.samad@example

memberof : group1

memberof : group2

dn: group2

member of group3

will the F5 see my id as member of group1 group2 group3 or just group1 group2

openldap doesn't support 1.2.840.113556.1.4.1941

seems like they never will - silly but
