Changing privileges via configuration files in undocumented

[x-yuri]

The docs says:

You can configure access entities using:

• SQL-driven workflow.
• Server configuration files users.xml and config.xml.

We recommend using SQL-driven workflow. Both of the configuration methods work simultaneously, so if you use the server configuration files for managing accounts and access rights, you can smoothly switch to SQL-driven workflow.

If you mention that one can use configuration files to change privileges, it should documented how that could be done. At least you should say why using configuration files is not recommended.
