`The config.py File`:index:
***************************

There are multiple configuration files that are read at startup by pgAdmin. These
files are used for configuration options that:

* may be required to be set prior to startup of pgAdmin as they control how
  the application will operate.
* system administrators may wish to control across an organisation to enforce
  security policies.
* are so rarely or unlikely to be changed that it doesn't
  make sense to allow them to be changed through the user interface.

The configuration files are as follows:

* ``config.py``: This is the main configuration file, and should not be modified.
  It can be used as a reference for configuration settings, that may be overridden
  in one of the following files.

* ``config_distro.py``: This file is read after ``config.py`` and is intended for
  packagers to change any settings that are required for their pgAdmin distribution.
  This may typically include certain paths and file locations. This file is optional,
  and may be created by packagers in the same directory as ``config.py`` if
  needed.

* ``config_local.py``: This file is read after ``config_distro.py`` and is intended
  for the owner of the installation to change any default or packaging specific settings
  that they may wish to adjust to meet local preferences or standards.This file is optional,
  and may be created by users in the same directory as ``config.py`` if
  needed.

* ``config_system.py``: This file is read after ``config_local.py`` and is
  intended for system administrators to include settings that are configured
  system-wide from a secure location that users cannot normally modify and that
  is outside of the pgAdmin installation. The location for this file varies
  based on the platform, and only needs to be created if desired.

.. note:: If the SERVER_MODE or DATA_DIR settings are changed in
     ``config_distro.py``, ``config_local.py``, or ``config_system.py``
     LOG_FILE, SQLITE_PATH, SESSION_DB_PATH, STORAGE_DIR, KERBEROS_CCACHE_DIR,
     and AZURE_CREDENTIAL_CACHE_DIR values will be set based on DATA_DIR unless
     values are explicitly overridden for any of the variable in any of the
     above file.
