ldap_connect problem in PHP4

Hi everybody, I have a problem using ldap_connect in PHP4. When I use : $ds = ldap_connect($server); I get on $ds a false (or negative) value, typical when was not possible to make the connection. However I'm sure on $server is runnning a LDAP server and on the default port (389). I checked this by using ldapsearch command at the same time when I'm trying to execute the php script and also by a C program I made using the OpenLDAP (the same library used by php) API for C. I wonder how can I debug what php is trying to do at a lower level to track this problem?
