#30107 [Opn->Bgs]: ldap_bind does a dns lookup for "localhost" (mod_php not CLI)

ID: 30107 Updated by: sniper@php.net Reported By: php at gunnarwrobel dot de -Status: Open +Status: Bogus Bug Type: LDAP related Operating System: Gentoo 2004.2 PHP Version: 4.3.8 New Comment: It's either a bug in openldap (unlikely) or misconfigured system of yours. Check your /etc/hosts and /etc/resolv.conf files. See also: http://www.netsys.com/openldap-software/2002/08/msg00020.html This is absolutely not a PHP bug whatsoever.. Previous Comments: ------------------------------------------------------------------------ [2004-09-16 10:27:11] php at gunnarwrobel dot de 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. TCPdump reports a request to the name server: 10:20:35.050539 IP myserver.mydom.info.41604 > dns2.arcor-ip.de.domain: 60613+ AAAA? localhost.
