[users@httpd] 302 endless loop with mod_auth_form config

[Thomas Eckert]

I'm looking for the erorr in this config :

KeepAlive OnServerName server1.domain1.localServerAdmin
me@domain1.localListen 10.10.10.10:80 http<Proxy
balancer://cd107d9706d71153bafd4ab15f1c6b5d>
        BalancerMember http://server1.domain2.local
status=-SE</Proxy><VirtualHost 10.10.10.10:80>
        ServerName secured.domain1.local
        SSLProxyEngine On
        RequestHeader set X-Forwarded-Proto http

        DocumentRoot /var/www/login_example/
        <Location /login/>
                SetHandler form-login-handler
                AuthFormLoginRequiredLocation
http://secured.domain1.org/login/example_form_template
                AuthFormLoginSuccessLocation http://secured.domain1.org/
                AuthFormProvider myprovider
                AuthType form
                AuthName realm
                Session On
                SessionCookieName session path=/
        </Location>

        <Location />
                ProxyPass balancer://cd107d9706d71153bafd4ab15f1c6b5d/
lbmethod=bybusyness
                ProxyPassReverse balancer://cd107d9706d71153bafd4ab15f1c6b5d/

                AuthFormProvider myprovider
                AuthType form
                AuthName realm
                AuthFormLoginRequiredLocation
http://secured.domain1.org/login/example_form_template
                Session On
                SessionCookieName session path=/
                Require valid-user
        </Location></VirtualHost>

Accessing / results in an endless loop of 302s to /login/. Putting
        <LocationMatch ^/(?!login/)>
on the second block did not change anything.
