debian - Apache + LDAP Auth: access to / failed, reason: require directives present and no Authoritative handler

Can't solve this one, here's my .htaccess:

AuthPAM_Enabled Off

AuthType Basic
AuthBasicProvider ldap
AuthzLDAPAuthoritative on

AuthName "MESSAGE"
Require ldap-group cn=CHANGED, cn=CHANGED

AuthLDAPURL "ldap://localhost/dc=CHANGED,dc=CHANGED?uid?sub?(objectClass=posixAccount)"
AuthLDAPBindDN CHANGED
AuthLDAPBindPassword CHANGED
AuthLDAPGroupAttribute memberUid

AuthLDAPURL is correct, BindDN and BindPassword are correct also (verified with ldapvi -D ..).

Apache version: Apache/2.2.9 (Debian)

The error message seems cryptic to me, I have AuthzLDAPAuthoritative on so where's the problem.

EDIT:

LDAP modules are loaded, the problem is not with them being missing.

# ls /etc/apache2/mods-enabled/*ldap*
/etc/apache2/mods-enabled/authnz_ldap.load  /etc/apache2/mods-enabled/ldap.load

EDIT2:

Solved it by changing funky

Require ldap-group cn=CHANGED, cn=CHANGED

line with

Require valid-user

Since AuthzLDAPAuthoritative is on, no other auth methods will be used and valid-user requirement will auth via LDAP. (right? :/)

Answer

Your 'Require' line reads

Require ldap-group cn=CHANGED, cn=CHANGED

That doesn't look write - I don't believe you can have have two cn's in a DN like that.
