I believe Kim is right about "factors in the default connection mode". In my own words: If no connection access permission has been set explicitly for a specific user, then the user inherits the default permission - and the SYSCS_UTIL.SYSCS_GET_USER_ACCESS system function takes this into account. 

The default permission (also known as the default connection mode) may be set by using the derby.database.defaultConnectionMode property, and is "fullAccess" by default (which has the same meaning as "FULLACCESS" in this context - it is unfortunate that different parts of the documentation refers to the same permission values with different casing, since the user may wonder if  this is the same value or not...). http://db.apache.org/derby/docs/dev/tuning/rtunproper24846.html .

A link to the manual page for derby.database.defaultConnectionMode would thus be nice, but it's no requirement.

The suggested phrasing "If no permission is set for the user, the setting for the default connection mode is returned." is OK. Do you think the following is clearer, or more confusing?

"If no permission is set explicitly for the user, the user's access permission is the value of the default connection mode".

I think another confusing element is that several different terms are used to describe the same thing in this context: "connection authorization", "connection mode", "access permission" and "access permissions", but that's a bigger issue which involves more than just these manual pages.
