Subject: Freeradius - LDAP Authenication
Hi All,
I'm rather new to radius and especially freeradius. I have the following
need. Cisco VPN needs to authenticate users against a Radius server, which
in turn needs to proxy the user authentication to our Sun One Iplanet LDAP
server (running on another machine). I have the vpn talking successfully to
freeradius, but I cannot get the onward connection to the LDAP to work. I
have validated that the server running freeradius is able to talk to the
ldap by using ldapsearch.
The config I am using is based upon the ldap_howto.txt under /docs.
I have searched the mailing list but to no avail.
Many Thanks in advance
Simon Barnes
