Not specific to embedded mode, Roman. In Fb 1.5.6, 2.0.5, 2.1.3 and 2.5.anything, only the SYSDBA (or equivalent) or Owner has write access to database header settings.

An embedded client doesn't go the server authentication route, so doesn't *need* a user name and password (and won't barf if they are not in the connection parameters). But the interface should be capable of accepting and storing a username for use in Services API calls...

Beware of enabling header-changing operations in a multi-thread environment, of course, regardless of the available user credentials...
