It is more the other way around; if you toggle it "off" and "on" where you definitely need the redirection to be disabled everything is fine, but if you set it to "off" at the start of the script (to ensure you are never redirected) it will break the group lookups.

This isn't just in 4.67, I've seen the issue in previous releases but have only just tracked it down to the ordering of the function calls.
