In version 1.13.1 (MySQL - 5.0.32-Debian_7etch6 & PHP Version 5.2.0-8+etch11) logged in users cannot modify sections due to an unknow database error. -->(Can't contact the database server: Unknown error (sql.example.it) Unlogged users have no problems.
Logged users cannot delete pages and append comments to discussion too.
I can't see any reason why the database would not connect for anonymous users but not for logged in users. If you can't contact the database server (as indicated by your error), it would seem to be that your database host, username or password is incorrect. Are you sure it's sql.example.it? Marking as WFM.
