The basic-lis-readmembershipsforcontextwithgroups option is something I 
added to the unofficial memberships extension to enable group 
information to be passed for WebPA.  I am not aware of this being 
implemented in anything other than the BasicLTI4Moodle module and the 
BasicLTI building block for Learn 9.  If you are seeing group 
information being included in the XML returned by Sakai, please can you 
send me a sample so that I can see if it is using the same format.

Stephen

PS Note that with the official IMS Memberships service now being in 
public draft, I would envisage that the use of the unofficial extension 
should be relatively short-lived, though the sharing of group 
information remains an outstanding issue.
