That's a great idea (& one I was aware of - thanks) but that doesn't answer my question :-)

Unless you are implying that my assumption was correct (ie DELETE, INSERT, SELECT, and UPDATE ).

Hi All,

I am enquiring as to the *minimum* privileges required by the RoundCube user to access the backend SQL (MariaDB) Server.

Yes, I am aware that the Wiki says (on the Installation page) to use GRANT ALL PRIVILEGES, as do all of the On-Line Tutorials scattered across the Web. However, that is a *massive* security hole, especially if the backend server is *not* the same as the web server hosting RoundCube. Surely, for example, the RoundCube User does *not* need the ability to create other users or tables, drop the backend database, or grant privileges to other users.

Thus, I am enquiring what *are* the *minimum* privileges required?

I am going to assume - and please correct me if I am wrong - that the *required* privileges are:

* DELETE, INSERT, SELECT, and UPDATE

If this information is available on-line, could someone please point me in the correct direction - if not, could one of the devs and/or one of the experienced RoundCube users please let me know this information - thank you.
