PHP Bug Type: LDAP related
Bug description: No RootDSE query possible
Description:
------------
I've found that searching the RootDSE does not work with
PHP, because the base is set to NULL when no base is
specified. This fact causes the LDAP library to look into
the systems ldap.conf to take the base from there - which
is probably not what we want.
The following patch fixes the problem:

Reproduce code:
---------------
<?php
# ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts
function get_naming_contexts($server, $admin, $password)
{
/* Build LDAP connection */
$ds= ldap_connect ($server);
if (!$ds) {
die ("Can't bind to LDAP. No check possible!");
}
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
$r= ldap_bind ($ds, $admin, $password);
/* Get base to look for naming contexts */
$sr = @ldap_read ($ds, "", "objectClass=*", array("namingContexts"));
$attr= @ldap_get_entries($ds,$sr);
print_r($attr);
}
get_naming_contexts("what.server.ever.org",
"cn=admindn,dc=whatever,dc=org", "secret");
?>
Expected result:
----------------
Array
(
[count] => 1
[0] => Array
(
[namingcontexts] => Array
(
[count] => 2
[0] => dc=whatever,dc=org
[1] => dc=whatever,dc=shell
)
[0] => namingcontexts
[count] => 1
[dn] =>
)
)
Actual result:
--------------
Array
(
[count] => 1
[0] => Array
(
[count] => 0
[dn] => dc=whatever,dc=org
)
)
