unix sockets and localhost and TLS

[Jason Joines <joines@bus.okstate.edu>]

   I've go OpenLDAP 2.2.15 running on SuSE Linux 9.2.  There is one 
master and several slaves.  The slaves run Samba and various other 
services that use ldap for authentication.  In this case, is if more 
efficient to reference the ldap server via localhost like 
ldap://localhost or via unix sockets like 
ldapi://%2fvar%2frun%2fslapd%2fldapi?  If using unix sockets, is TLS 
even applicable?  If not, will enabling TLS in slapd.conf disable access 
to the unix socket?

Thanks,
