SOGo is working and configured to use MariaDB as backend SQL database.
But why does it store SQL username and plain password in SQL table sogo_folder_info, columns c_location, c_quick_location and c_acl_location?
I understand it needs SQL access, but can we keep SQL username and passwords in just sogo config file /etc/sogo/sogo.conf?
Similar issue, while backup sogo data for user with LDAP backend, it dumps full LDAP data of this user in stored in backup file (ldif_record), is it really necessary?

[sogo]> select * from sogo_folder_info \G
