I've installed my moodle site on Linux (Ubuntu) server. I have PHP (Version 5.0.5-2ubuntu1.1). I want to authenticate the users fron a LDAP server. When I go to "Administration » Users » Authentication options" and set to "Use an LDAP server" I get a message "Warning: The PHP LDAP module does not seem to be present. Please ensure it is installed and enabled."
I'm looking how to enable the PHP LDAP module (extension?) in my moodle installation and I cannot find a way to to that.
Can anybody help me? What should I do to enable the PHP LDAP module in Linux?
