	Ok, but this is not Samba part of the job. :)

	If Samba is not talking with your LDAP server, then this
parameter has no effect. You should do the TLS/SSL configurations
on your LDAP server. And you should use kerberos to have real
security in your smb network.

	If it is a PEM with private certificate, shouldn't be
world readable.

	Increase the log level on slapd.conf.

	Ok, it is a configuration of libldap and other software
that will use resources to query LDAP server. But AIUI you are
not using Samba to query LDAP, you are using winbind to do that,
and then, your question is a little bit off-topic here. ;)
