[racktables-users] Adding new params in secret.php

Hi, list:

I'm trying to modify the LDAP procedure hacking a bit authenticated_via_ldap 
at inc/auth.php.  For this I need to add some new vars at secret.php (i.e.: 
some $ldap_basedn).  They seem to be declared global somewhere else (maybe at 
init.php) but I don't see how they are processed.  Can someone help me about 
the proper way to manage these kind of config params?

TIA.
