# STORE THE CONFIG FILE CHECKSUM
#=================================================

### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.

# Calculate and store the config file checksum into the app settings
#ynh_store_file_checksum "/etc/onlyoffice/documentserver/nginx/onlyoffice-documentserver.conf"

# SECURE FILES AND DIRECTORIES

### For security reason, any app should set the permissions to root: before anything else.
### Then, if write authorization is needed, any access should be given only to directories
### that really need such authorization.

# Set permissions to app files
#chown -R root: /etc/loolwsd


#=================================================
# SETUP SSOWAT
#=================================================

# If app is public, add url to SSOWat conf as skipped_uris

  # unprotected_uris allows SSO credentials to be passed anyway.
