rlm_ldap: could not start TLS

Hi, I'm trying to make freeradius 1.1.0 contact a LDAP server. I configured freeradius --with-edir. The error I get is "rlm_ldap: could not start TLS Can't contact LDAP server" I followed this document http://www.novell.com/coolsolutions/tip/15922.html except that in my case, the LDAP server is on Netware 6.5 SP5. On this Netware server, LDAP responds correctly over SSL, as tested with Novell's ldapsearch on port 636. In radiusd.conf, in the ldap section, I use tls_cacertfile = /usr/local/freeradius/etc/raddb/certs/rootder.b64 which is the self-signed certificate exported from the Netware's CA object. I can provide other details about my "LDAP server" object in Netware upon request. Thanks in advance, Marc Delisle
