| | |
| 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
| |
| | |
| Example:
| |
| | |
| #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:
| |
| a2enmod proxy_http
| |
| | |
| 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"):
