Jeffrey, The script looks like what i want to be able to do with contact list. I have a problem though... it doesn't seems to work for me. Here is the error i get from my server: Fatal error: Call to undefined function: ldap_connect() in c:\inetpub\wwwroot\ldap_exchange.php on line 2 It looks like i can't connect to my LDAP server. I know it is working fine. Is ther something has to be activated on my server??? Here is my settings i put in the script: <?php $ds=ldap_connect("172.16.8.5"); $dn = "cn=administrator, cn=users, dc=casinomontelago, dc=com"; $password = "*****"; if ($ds) { $r=ldap_bind($ds, $dn, $password); $sr=ldap_search($ds,"cn=users, dc=casinomontelago, dc=com", "mailnickname=".$uid); $info = ldap_get_entries($ds, $sr); Vadim. -----Original Message----- From: Jeffrey Robillard [mailto:jrobill@xxxxxxxxxxxxx] Sent: Friday, July 18, 2003 11:06 AM To: [ExchangeList] Subject: [exchangelist] RE: custom contact list http://www.MSExchange.org/ This is a multi-part message in MIME format.
