Hi, I'm trying to use the ldap_parse_reference LDAP function. I have the following error message : Fatal error: Call to undefined function: ldap_parse_reference I upgraded PHP from 4.3.4 to 4.3.9 (latest stable) but the problem remains. Other ldap functions like ldap_connect or ldap_search do work properly. I found some bug reports about this error, but I guess the missing functions should have been added to the latest release... I added the 2 dlls for ldap to work. Do I need to install something other for these functions? Any other idea? Vincent
