[Zope] UserDb/Authentication Questions

I found that if you create a page wich define __name and __password, eg:

**MyLoginPage**
<form action=LoginSuccessfull method=post>
<input type=text name=__name>
<input type=text name=__password>
<input type=submit>
</form>

**LoginSuccessfull**
<p>You have logged in!</p>

If __name and __password are correct, the user is automagically
logged with that name and that password, and the LoginSuccessfull
page is displayed.

However, if the __name and the __password aren't correct, you get
the unauthorized page.

To Logout the user, MyLogoutPage expire the __ac cookie.

However I didn't like these way of doing. So I wrote an exthernal method
that
compute an __ac value from two variables: name and password (not __name
and __password, to avoid acl_users do the authentification itself), or
return
None if these are not correct.
That way, if the result is not None, I set a cookie with name __ac and the
value
I got from the external method.

You could write your own external method by looking at the source of UserDb.
