openldap ssl/tls not getting started

Hi,

I am using openldap-2.4.19-4.fc12.x86_64 on fedora 12 machine. I want to start slapd with ssl/tls enabled. I have followed all the necessary steps as per specified in admin guide but still slapd not getting started in ssl/tls mode. Whenever I do ldapsearch with -ZZ option, it shows can't contact LDAP server(-1).

Can anybody tell me the detailed steps and settings so that I can match those with my followed steps?

Server file names are as follows: /etc/openldap/slapd.conf /etc/openldap/ldap.conf /etc/ldap.conf /etc/nsswitch.conf

Client file names are as follows: /etc/openldap/ldap.conf /etc/ldap.conf /etc/nsswitch.conf
