 *  LOGLEVEL_FATAL          - log only critical errors
 *  LOGLEVEL_ERROR          - logs events which might require corrective actions
 *  LOGLEVEL_WARN           - might lead to an error or require corrective actions in the future
 *  LOGLEVEL_INFO           - usually completed actions
 *  LOGLEVEL_DEBUG          - debugging information, typically only meaningful to developers
 *  LOGLEVEL_WBXML          - also prints the WBXML sent to/from the device
 *  LOGLEVEL_DEVICEID       - also prints the device id for every log entry
 *  LOGLEVEL_WBXMLSTACK     - also prints the contents of WBXML stack
 *
 *  The verbosity increases from top to bottom. More verbose levels include less verbose
 *  ones, e.g. setting to LOGLEVEL_DEBUG will also output LOGLEVEL_FATAL, LOGLEVEL_ERROR,
 *  LOGLEVEL_WARN and LOGLEVEL_INFO level entries.

/*
 *  Synchronize additional folders to all mobiles
 *
 *  With this feature, special folders can be synchronized to all mobiles.
 *  This is useful for e.g. global company contacts.
 *
 *  This feature is supported only by certain devices, like iPhones.
 *  Check the compatibility list for supported devices:
 *      https://grommunio.com/
 *
 *  To synchronize a folder, add a section setting all parameters as below:
 *      store:      the resource where the folder is located.
 *                  grommunio users use 'SYSTEM' for the 'Public Folder'
 *      folderid:   folder id of the folder to be synchronized
 *      name:       name to be displayed on the mobile device
 *      type:       supported types are:
 *                      SYNC_FOLDER_TYPE_USER_CONTACT
 *                      SYNC_FOLDER_TYPE_USER_APPOINTMENT
 *                      SYNC_FOLDER_TYPE_USER_TASK
 *                      SYNC_FOLDER_TYPE_USER_MAIL
 *                      SYNC_FOLDER_TYPE_USER_NOTE
 *      flags:      sets additional options on the shared folder. Supported are:
 *                      DeviceManager::FLD_FLAGS_NONE
 *                          No flags configured, default flag to be set
 *                      DeviceManager::FLD_FLAGS_SENDASOWNER
 *                          When replying in this folder, automatically do Send-As
 *
 *  Additional notes:
 *  - use lib/grommunio/listfolders.php script to get a list of available folders
 *
 *  - all grommunio-sync users must have full permissions so the configured
 *    folders can be synchronized to the mobile. Else they are ignored.
 *
 *  - this feature is only partly suitable for multi-tenancy environments,
 *    as ALL users from ALL tenants need access to the configured store & folder.
 *    When configuring a public folder, this will cause problems, as each user has
 *    a different public folder in his tenant, so the folder are not available.
 *
 *  - changing this configuration could cause HIGH LOAD on the system, as all
 *    connected devices will be updated and load the data contained in the
 *    added/modified folders.
