In the setup-kolab intro, make it abundantly clear that the System FQDN used must adhere to strict conditions;
- For the system on which Kolab is installed, the FQDN must resolve back to the system in question.
- The system FQDN may resolve back to 127.0.0.1, but this won't help with the other conditions.
- The system FQDN is also used to negotiate access between the Roundcube Kolab Plugins and Manticore, and must therefore also resolve for the outside world.
- This may be amended such as using demo01.example.org for the system FQDN, with the URL used in browsers being demo.example.org.
