Reverified during bughunt. From the user-comments:

"When using an URI to describe the connection, the (open)ldap library
only parses the url and checks if it's valid, _no connection_ is
established in that case."

This is not an PHP/ldap bug but a documentation problem it seems to
me.

When using an URI to describe the connection, the (open)ldap library
only parses the url and checks if it's valid, _no connection_ is
established in that case.

Checking the return code of ldap_bind() would be the proper thing to do
anyway.

I'm running a very simple test script (see below) to test my ldap
server connection. According to the docs, ldap_connect() is supposed
to return an LDAP resource id on successful connect, or FALSE on error.
 When I run the code with a valid server URI ($ds =
ldap_connect("ldap://ldap.example.com")), everything works fine. When
I run it with a URI to a nonexistent LDAP server ($ds =
ldap_connect("ldap://does.not.exist")), ldap_connect returns a resource
ID anyway, so my script has no way of knowing anything is wrong until I
try to bind or search. If I simply give a nonexistent hostname rather
than a URI ($ds = ldap_connect("does.not.exist")) the function returns
FALSE as documented.

I built PHP 4.1.1 against the client libraries from OpenLDAP 2.0.21.
Here's the full code of my test script:

<?php
$ds = ldap_connect("ldap://ldap.example.com/");
echo "connect result is ".$ds."<p>";
if($ds) {
  $r=ldap_bind($ds);
  echo "Bind result is ".$r."<p>";
  $sr=ldap_search($ds, "ou=users,dc=example,dc=com", "uid=carljm");
  echo "Search result is ".$sr."<p>";
  echo "Number of entires returned is
".ldap_count_entries($ds,$sr)."<p>";
  echo "Getting entries ...<p>";
  $info = ldap_get_entries($ds, $sr);
  echo "Data for ".$info["count"]." items returned:<p>";
  for ($i=0; $i<$info["count"]; $i++) {
    echo "dn is: ". $info[$i]["dn"] ."<br>";
    echo "first cn entry is: ". $info[$i]["cn"][0] ."<br>";
    echo "first uidNumber entry is: ". $info[$i]["uidnumber"][0]
."<p>";
    }
echo "Closing connection";
ldap_close($ds);
?>
