Subject Re: Using Eve as a proxy to an existing LDAP server - Interceptor HOW-TO
Date Tue, 16 Aug 2005 14:30:57 GMT
Ah, yes.  You are 100% correct in your assumptions then.  BTW, there
is already a virtual directory (based on apacheds) Called Penrose. 
I've not tried it but I think it has a mapping capability in addition
to proxy support.
