The goal here is to authenticate a user for the Open-Xchange system from an external system and to safely pass on the received session data to the user´s browser. To do so the external system has to know the user data (username, password) for Open-Xchange in plain text.
There are three participants in this process: User, Open-Xchange system ("OX") and External system ("3rd-party").
== Prerequisites ==
1. A ReverseProxy-directive has to be set in the OX-/Loadbalancer-Apache
#ReverseProxy to 3rd-party to enable the form-login
ProxyPass /forwardname http://3rdpartydomain.tld
ProxyPassReverse /forwardname http://3rdpartydomain.tld
#enable sslProxy
SSLProxyEngine on
please note that "forwardname" is just an example, this could be anything
2. The necessary apache-module needs to be installed for this directive to work
Typically that is done like this:
ln -s /etc/apache2/mods-available/proxy_http.load /etc/apache2/mods-enabled/proxy_http.load
3. The 3rd-party system accesses the OX-system via the same domainname as the user (e.g. oxdomain.TLD)
4. the 3rd-party system is on the ip-check-whitelist of the OX-system as described here (in "10.2.20. noipcheck.cnf"):
Also the exact parameter-names for the FormLogin can be found here:

This diagram shows the complete process. Just read it naturally from top to bottom and you have the chronological oder things need to happen in.
