gnue-appserver authentication

Hello!

Could someone point me to an example to integrate user authentication
with the gnue-appserver?

From what I've read in the white paper and the sample directory, I would
need to import the samples/auth.gcd file into my project.  Then I would
expect to be able to manage the access of users to certain classes.

This is a good start, but I also need is to manage access to certain
forms.  Also access to the certain classes (like I would imagine the
gnue_useraccess class itself) on which a user should be allowed to read
other user entries with the exception of the password yet only be
allowed to write a certain qualified subset.

I'm currently trying to create a .gld to then derive a form to
gracefully handle password.  But I'm missing a style property for fields
that bullet replaces the entered characters with bullets.  Is this
feature missing or just not documented (or did I miss the documentation)?

Cheers,
David
