Not directly related to this issue, but a resolution to an annoyance I
had...

It appears that all sorts of docs for Windoze people/machines are everywhere
while those of us who have an all-Posix environment are left to fend for
ourselves.  Even Apache's documentation doesn't directly address posix hosts
(Linux) connecting via Apache authentication back to an LDAP server serving
up a UNIX authentication system.

So, the next person who searches for that on our little family list here, I
want to help out.

Here's my solution:

ScriptAlias /xymon-seccgi/ "/home/xymon/cgi-secure/"
<Directory "/home/xymon/cgi-secure">
    AllowOverride None
    Options ExecCGI Includes
    Order deny,allow
    Deny from all
    AuthName "Xymon Administration"
    AuthType Basic
    AuthBasicProvider ldap
    AuthzLDAPAuthoritative Off
    AuthLDAPURL ldap://nst-ldap.foo.com/dc=foo,dc=com?uid
    AuthLDAPBindDN "cn=ldapadmin,dc=dc=foo,dc=com"
    AuthLDAPGroupAttribute memberUid
    AuthLDAPGroupAttributeIsDN off
    AuthLDAPBindPassword PASSWORD
    Require ldap-group cn=admins,ou=Group,dc=foo,dc=com
    Require ldap-attribute gidNumber=505
    Satisfy any
</Directory>

This allows me to authenticate against the store as any member of the group
"admins" that has a Group ID in Linux-land of 505.

For just a user anywhere in the store:

ScriptAlias /xymon-seccgi/ "/home/xymon/cgi-secure/"
<Directory "/home/xymon/cgi-secure">
    AllowOverride None
    Options ExecCGI Includes
    Order allow,deny
    Allow from all
    AuthName "Xymon Administration"
    AuthType Basic
    AuthBasicProvider ldap
    AuthzLDAPAuthoritative Off
    AuthLDAPURL ldap://nst-ldap.foo.com/dc=foo,dc=com?uid??(objectclass=*)
    AuthLDAPBindDN "cn=ldapadmin,dc=foo,dc=com"
    AuthLDAPBindPassword PASSWORD
    Require valid-user
</Directory>

it took a number of edits all over the place and restarts to get this
working, but I wanted to share for those in the same situation as I.


To get caught by the search at Hobbiton:

Apache mod_authnz_ldap groups authenticate httpd AuthLDAP cgi-secure seccgi

That ought to do it.

Thanks Matt, can't wait to try this out!

Here is our configuration in /etc/httpd/conf.d/hobbit-apache.conf
that allows us to authenticate against AD. Took a lot of searching
to find the solution, which was pretty obscure, so hopefully this helps.
I've removed the default comments, so you may want to put them back
or have your own.


Note the "AuthzLDAPAuthoritative
Off" ... that was the kicker in getting it all to play nice.


AllowOverride None

Options ExecCGI Includes

Order allow,deny

Allow from all

AuthType Basic

AuthBasicProvider ldap

AuthGroupFile

AuthLDAPURL
"ldap:///dc=example,dc=domain,dc=com?sAMAccountName?sub?(objectClass=*)"
AuthName "Xymon Admin
- Use your Windoze password"

AuthzLDAPAuthoritative
off

Require valid-user

Require group

AuthLDAPBindDN
"CN=_,OU=,OU=,DC=example,DC=domain,DC=com"

AuthLDAPBindPassword
""

Really? You know of a way in which I can auth against AD and based
on
page/pages in apache?
Pages and subpages are just physical directories below
~hobbit/server/www/
so you can setup standard Apache ""
definitions to impose
access restrictions.
As for authenticating against an AD, you must use the Apache
mod_auth_ldap
module. If you google "apache auth active directory" it
should give you
some hints.
