Modifying configuration files

For Password Sync 3.0.0 and later, syntax check for configuration files (config.yml, secret.yml) in YAML format has become stricter.
For this reason, an error may occur when a configuration file is read if there is a grammatical error in its description, even if the configuration file can be used for a version earlier than Password Sync 3.0.0.

When updating your current version to Password Sync 3.0.0 or later, check whether configuration files are described with correct syntax, and if there are descriptions with incorrect syntax, correct them in advance.
