The Configuration file config.php

Like many other programs Admidio also provides a central configuration file, in which the most important settings are stored. You'll find the file in the folder adm_my_files (up to and including 2.4 Admidio the file was directly saved in the Admidio main folder). It is automatically created during the installation and stored there. Usually it is no longer necessary to open and edit. In rare cases, but this may still be necessary, for example, while moving the Admidio folder or to activate a more detailed logs. For this reason we want to give you an overview of the existing and possible settings in the file, as well as a explanation of each setting.

Any user, whether logged out or logged in, will have a unique session ID. This ID is passed on every page request. If a foreign person is now scanning the traffic between the computer and the server and gets access to this ID, he could assign with this session ID as current user. He therefore would has all the rights in the system that owns the original user. To prevent this abuse, Admidio compares additionally on every page request, the associated IP address to this session. If the IP address changes in between, so Admidio recognizes this as an invalid connection and closes the corresponding session.

This setting is always enabled and does not need to be explicitly set in config.php. Are there, however, some users having problems or some users are using deliberately Services that change the IP address on a regular basis, so the test can be disabled.
