Bug #15389 Updated: slow ldap connect

ID: 15389 Updated by: venaas@php.net Reported By: martin@kouba.at Status: Open Bug Type: LDAP related Operating System: w2k advanced server PHP Version: 4.1.1 New Comment: Have you tried to connect to the LDAP server with something else than PHP? Some other LDAP client, or even telnet to the LDAP port? One possibility is that the LDAP server spends some time trying to lookup the clients hostname in order to check access or log the name.

I might be able to check it.

Try connecting to the server with another client. (reclassified) ------------------------------------------------------------------------ [2002-02-05 12:51:25] martin@kouba.at i tried the ldap functions with php 4.0.6 and now with 4.1.1. the ldap queries are super fast, but the connect takes 4 to 5 seconds. first i thought it was the queries but when i removed the queries the script would still take the same time to execute. the queries would only take about 1 second to compute. i already use the ip address of the ldap server for the connect to avoid dns lookups. i understand that any connect procedure takes a while but for the user to wait for 5 seconds is much too long. is there a way to optimize the connect procedure? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15389&edit=1
