Unfortunately, this doesn't work: if sssd can't determine the group
type, it filters ALL groups, instead of filtering no groups.

Hmmm.  If sssd can't determine the group type, wouldn't it be better
to filter no groups, instead of all groups?  Because filtering all
groups is essentially the same thing as disabling group lookups
entirely.  That doesn't seem like the best behavior to choose.

Then again, maybe a cleaner approach would be to add a
ldap_group_filtering option, and make the default value true (filter
groups that aren't security groups)?  Tricking sssd by telling it to
look at the wrong field for the group type seems like a hack.  :-(
