Authentication using LDAP on port 636

Hi, I installed freeradius 1.0.1 for RHEL4 from RedHat network. As an ldap server I have Sun Directory server 5.2 patch3 with SSL enabled. I have plenty of applications using port 636 to access LDAP (ypldapd from padl, /etc/ldap.conf on linux, Mozilla address book, etc..) . With freeradius as long as I use standard port 389 I don't have problems to use LDAP, but I have problems to use port 636 (Can't contact LDAP server). Or I missed something but I seem to be unable to find a procedure how to setup freeradius using SSL. Any help would be appriciated Thanks, Dany
