# Use mod_authz_groupfile to store money/root

# Whenever groups are updated in the portal, write the file
# make sure to store the file outside of the web root (duh)
# only users in money/root can do reject/adduser
# common code should go into a module (feh!)

# member_payment in another (only kerberos users)

# If there is a way to allow all and check the group info

# alt: libapache2-mod-authnz-external + db helper script
# can use ExternalGroup, check kerberos user is in group specified in
# another env var
