Thread:Extension talk:LDAP Authentication/why is it "Doing an anonymous bind" instead of using the username and password i entered?/reply (13)

This is failing: $bind = @ldap_bind( $this->ldapconn, $userdn, $password );

With this error: Warning: ldap_bind [function.ldap-bind]: Unable to bind to server: Can't contact LDAP server in

I suspect it is a bug with PHP. I am using 5.3.6 on a windows 2008 R2 box with IIS.
