If my user is authenticated, Attributes from respective user *and* from DEFAULT user are replied to the nas although there is no explicit "Fall-Through = Yes" attribute. Is that an excpected behaviour ?

  Yes.  The "files" module and the "sql" module run completely independently.

  Fall-Through is only applied inside of one module.  e.g. for entries in the "users" file.  It doesn't affect inter-module behaviour.

  Have the DEFAULT entry in the "users" file set a special attribute, and then check for that.

  That's good.  And then wrap the call to the SQL module with a check for this situation:

	if (reply:Class ~= "Default") {
