So there is no way if we are using OpenLDAP to
distinguish betweeen:

* server is up and pingable
* LDAP server is running

?

I added sniper's comments to the ldap_connect() docs but am leaving
this bug report open until a doc member more familiar with LDAP can
close out this bug.  Here's the commit:

My solution was to go one step further by using 'ldap_bind' to test the
connection :
$ds=ldap_connect("titi.tata.net");
$r=@ldap_bind($ds,"cn=toto","tutu");
if ($r) {
bla bla bla
}
else die("LDAP server not accessed !");
The '@' before 'ldap_bind' disables Warning dysplay.

I was trying to test my code which supposed to tell me whether a LDAP
server is alive and rechable or not. But no matter what IP address I
specified in ldap_connect it returned a valid resource.

I found a way out by first pinging the server to know whether its alive
and then trying to bind to know whether it is running LDAP.

I can't get ldap_connect to return false, even when I
pass an invalid URI or an invalid hostname. At least, I
think ".*&%^$ldap.central.susx.ac.uk" is an invalid
host name, and so is "4". They both return ldap
connection resources, though.

It is important, because I need to be able to test the
hostname validity so that i know whether the problem
with the host is that (a) it doesn't exist (b) it is
down (c) the ldap service is down.

So, is there a way to find whether the LDAP server is valid or not ?
