Hi Gaël,
I'm a bit of an LDAP noob from the administrative side, I've only connected and queried information from Java Applications. I've installed OpenLDAP on CentOS 4.3, I'm connecting to LDAP from a Fedora 6 box with Apache 2.2. I have it partially working thanks to your response! I missed the "AuthzLDAPAuthoritative directive be set to off" for require valid-user. I have the following configuration and it now works for all employee access, but I want to limit it to only developers. The posix group "developers" path is below
cn=development,ou=Groups,dc=arocksoftware,dc=com
The member attribute in the development group is "memberUid" for the user id of all members

I tried change the config below to the following parameters, and it won't authenticate with the require group on. If I comment out the group directive and just go with require valid user, it works. Can I get any help on what's wrong with my group query string?

Thanks,
Todd

I personally always look on the ldap back-end side to see the query
string being issued. Which ldap directory are you using

Before working with a group, do you have the ldap authentication
working for a single user?

"require valid-user" directive requires that mod_authz_user be loaded
and that the AuthzLDAPAuthoritative directive be set to off but you
have it set to off
(http://httpd.apache.org/docs/2.2/mod/mod_authnz_ldap.html#reqvaliduser ).

AuthLDAPGroupAttribute specifies which LDAP attributes are used to
check for group membership.
The require directives are used during the authorization phase: are
you sure you're right in specifying both require valid-user and
require ldap-group? As said a few lines below, require valid-user
require an additional authorization modules (mod_authz_user). Why
don't use only require ldap-group? This whay you could let
"AuthzLDAPAuthoritative On"?
