Operating system: Gentoo 2004.2
PHP version: 4.3.8
PHP Bug Type: LDAP related
Bug description: ldap_bind does a dns lookup for "localhost" (mod_php not CLI)
Description:
------------
After connecting to OpenLDAP on "localhost" subsequent binding fails.
This only happens in mod_php, not with CLI.
Apparently the ldap_bind function of mod_php is unable to resolve
"localhost".
This might be related to bug #29587
Regards
Gunnar
Reproduce code:
---------------
<?
$ds=ldap_connect("localhost", 389);
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
if(!ldap_bind($ds,"uid=myuid,dc=mydom,dc=de","mypass"))
{
print "<br />Error<br />";
print(ldap_error($ds));
}
?>
Expected result:
----------------
No error.
Actual result:
--------------
Error
Can't contact LDAP server.
