I want to create my moodle application authenticate with LDAP. My Active Directory is in AWS EC2 Windows Instance. When I try to create authentication, it shows me an error like this: "LDAP paged results not supported (either your PHP version lacks support, you have configured Moodle to use LDAP protocol version 2 or Moodle cannot contact your LDAP server to see if paged support is available.) "
Ok, so you have lots of options there - have you checked them all?
