Aha! My account's group is "domain users" (with the space), coming from
the SSSD/Active Directory login management. So Apache is seeing GROUP
domain users, and thinks there are two parameters because of the space.
Googling, I see other mentions of "domain users" group with AD-managed
linux boxes. If you had GROUP "${MOD_WSGI_GROUP}" (with the quotes) in
your template, I think Apache would be happy, with no side effects? Or
perhaps using "#-1" (the 'omitted' indicator) instead of looking up and
filling in the current user's group with your default_run_group produce the
correct result in all cases?
