Same helper API protocol as for the auth helper you wrote. Only the
input line changes.

The helper receives the format-string from the ldap_group definition
followed by the text " students" on its stdin.

PS. if you looked above in the auth_param descriptions you will see
group= kv-pairs being accepted in from the auth helpers. You can use
those with a note ACL matching group names instead of a second helper.
