A few notes:

Our DNS servers are configured with SRV records for our LDAP server, 
hence the _srv_ token in the ldap_uri directive, e.g.,

   [bash]$ dig +nocmd _ldap._tcp.blah.com -t srv +noall +answer
   _ldap._tcp.blah.com.  3600  IN  SRV  1 0 389 ldap-1.blah.com.
   _ldap._tcp.blah.com.  3600  IN  SRV  0 0 389 ldap-2.blah.com.

Second, we use a local certificate authority to issue and sign 
internal-use certificates. The CA cert is installed in 
/etc/openldap/cacerts and cacertdir_rehash is run against it. In fact, 
we do that at kickstart time, e.g.,

   %post
   # import CA certificate and rehash it for LDAP/TLS
   curl http://www.blah.com/ca/ca.blah.com.pem \
      -s -o /etc/openldap/cacerts/ca.blah.com.pem
   /usr/sbin/cacertdir_rehash /etc/openldap/cacerts
