I followed the instructions in
http://fimspecialist.blogspot.com/2013/03/to-make-security-option-visible-to-non.html#!/2013/03/to-make-security-option-visible-to-non.html
to allow non-admin users to see the SG options on the portal. When I log in
with my non-admin account I see the links to My SG's and My SG Memberships.
I have added my non-admin account to an SG (TestGroup1), which does have Owner and Displayed Owner attributes set.

I made that account a member of the Security Group Users set.
When logged into the portal I can search All Security Groups, I see TestGroup1 and see myself as a member.
The issue is, when I click on My SG Memberships, there are no results.
