+If <application>libpq</application> has been compiled with LDAP support (option
+<literal><option>--with-ldap</option></literal> for <command>configure</command>)
+it is possible to retrieve connection options like <literal>host</literal>
+or <literal>dbname</literal> via LDAP from a central server.
+The advantage is that if the connection parameters for a database change,
+the connection information doesn't have to be updated on all client machines.
+</para>
+
+<para>
+LDAP connection parameter lookup uses the connection service file
+<filename>pg_service.conf</filename> (see <xref linkend="libpq-pgservice">).
+A line in a <filename>pg_service.conf</filename> stanza that starts with
+<literal>ldap://</literal> will be recognized as an LDAP URL and an LDAP
+query will be performed. The result must be a list of <literal>keyword =
+value</literal> pairs which will be used to set connection options.
+The URL must conform to RFC 1959 and be of the form
+<synopsis>
+ldap://[<replaceable>hostname</replaceable>[:<replaceable>port</replaceable>]]/<replaceable>search_base</replaceable>?<replaceable>attribute</replaceable>?<replaceable>search_scope</replaceable>?<replaceable>filter</replaceable>
+</synopsis>
+where <replaceable>hostname</replaceable>
+defaults to <literal>localhost</literal> and
+<replaceable>port</replaceable> defaults to 389.
+</para>
+
+<para>
+Processing of <filename>pg_service.conf</filename> is terminated after
+a successful LDAP lookup, but is continued if the LDAP server cannot be
+contacted. This is to provide a fallback with
+further LDAP URL lines that point to different LDAP
+servers, classical <literal>keyword = value</literal> pairs, or
+default connection options.
+If you would rather get an error message in this case, add a
+syntactically incorrect line after the LDAP URL.
