I have found will be able to access HTTP Authorization header through the following code

RewriteEngine on
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]

Regrettably I do not learn how to decode it from base64 after which split account information.

Obviously it is easy to get this done outdoors apache config, however i need user title and password within the config to be able to pass these to LDAP authorization module.

Really I wish to make a move such as this:

<Directory "C:/my/directory">
    WSGIApplicationGroup %{GLOBAL}
    Order deny,allow
    Allow from all

    AuthType Basic
    AuthName "Trac"
    AuthBasicProvider "ldap"
    AuthLDAPURL "ldap://domain.local:3268/DC=domain,DC=local?sAMAccountName?sub?> (objectClass=user)"
    AuthLDAPBindDN       %{HTTP_USER}@domain.local
    AuthLDAPBindPassword %{HTTP_PASSWORD}

    AuthzLDAPAuthoritative off

    Require valid-user

I want this because our LDAP server does not accept anonymous demands.
