Kim Haase commented on DERBY-3334:
----------------------------------

Although the examples make it pretty clear what is going on, the terminology is imprecise and could be tidied up.

> Java doc for UserAuthenticator class should clearly state the input format for user name.
> Currently the javadoc uses the terms "case-insensitive authorization identifier" and "case-sensitive authorization identifier", which is incorrect. Authorization identifiers are always case sensitive, it's their representation as user names that has the appearance of being case insensitive.
> Note that user names are not really case sensitive or case insensitive, non-delimited names are upper-cased to become an authorization identifier.
> This wiki page has the SQL rules that lead to this behaviour.
