Dear @anayrat , you totally made a good point.

The readme should state something like this: "[..] Although DAL might allow the use of different database management systems (DBMSs) (e.g., MariaDB, MySQL, PostgreSQL, SQLite, MsSQL, etc.), it is important to note that daloRADIUS has been fully tested only on the MariaDB DBMS. Therefore, the use of other DBMSs is not recommended. [..]".
