   3 #    This CGI script might be useful for providing an easy way for EZproxy to authenticate
   4 #    users against an Evergreen instance.
   5 #
   6 #    For example, if you modify your eg.conf by adding this:
   7 #    Alias "/cgi-bin/ezproxy/" "/openils/var/cgi-bin/ezproxy/"
   8 #    <Directory "/openils/var/cgi-bin/ezproxy">
   9 #        AddHandler cgi-script .pl
  10 #        AllowOverride None
  11 #        Options +ExecCGI
  12 #        allow from all
  13 #    </Directory>
  14 #
  15 #    and make that directory and copy remoteauth.cgi to it:
  16 #    mkdir /openils/var/cgi-bin/ezproxy/
  17 #    cp remoteauth.cgi /openils/var/cgi-bin/ezproxy/
  18 #
  19 #    Then you could add a line like this to the users.txt of your EZproxy instance:
  20 #
  21 #    ::external=https://hostname/cgi-bin/ezproxy/remoteauth.cgi,post=user=^u&passwd=^p
