I don’t understand the difference between /etc/ldap/ldap.conf and /etc/default/slapd

ldap.conf is the client configuration file, see ldap.conf(5). Parameter 'uri' defines the default LDAP server used.

/etc/default/slapd is probably a configuration file for the init script on your Linux distribution (Debian I guess). You have to ask the distribution package maintainer about that.

For exemple, what is the difference between URI and SLAPD_SERVICES ?

You should look in the init script how SLAPD_SERVICES is used on your distribution.

I want to authorise LDAP protocol only from localhost and only LDAPS for the external… How can I do this ?

I'd recommend to check out these directives in slapd.conf(5) for static configuration: security localSSF

Or when using back-config see slapd-config(5) for the accompanying LDAP attrs.
