500 Internal Server Error with LDAP

Hi All,

* I have such apache configuration for a site, which uses LDAP to authenticate people:

<VirtualHost 111.111.111.111:81>
        ServerAdmin test
        ServerName some.domain.com:81
        DocumentRoot /var/www/test/public_html

        <Directory /var/www/test/public_html/>
                Options All
                AllowOverride All

                AuthLDAPUrl "ldaps://something.com:636/ou=people,o=org?uid?sub?(&(objectClass=*)(personType=whatever))"
                AuthName "your password"
                AuthType Basic
                AuthBasicProvider ldap
                Require valid-user
                AuthzLDAPAuthoritative Off

                order deny,allow
                deny from all

                Satisfy Any
        </Directory>
</VirtualHost>

Code (markup):

- When login, it says "500 Internal Server Error", no matter my username & password are correct or not.

- I use Debian Lenny as server and I set TSL_server never in ldap.conf for testing purpose. (Because it queries ldaps://.......). It is still not working.

- Do you think if I install the certificate, then it will work? Or is there anything wrong inside the <Directory>?
