[Zope] authenticated_user in Z SQL method not defined

[Christoph Landwehr]

Hi,

I'm using the exUserFolder together with a PostgreSQL-db to log in 
users. Works so far.

With <dtml-var "AUTHENTICATED_USER.getUserName()"> I get the username 
which is the same as the field "username" in the db users.

But I can not use AUTHENTICATED_USER in an sql-querry like
SELECT foo
FROM users
WHERE username=<dtml-var "AUTHENTICATED_USER.getUserName()" sql_quote>;

Why is AUTHENTICATED_USER not availabel in  Z SQL methods?

Traceback (innermost last):
     * Module ZPublisher.Publish, line 98, in publish
     * Module ZPublisher.mapply, line 88, in mapply
     * Module ZPublisher.Publish, line 39, in call_object

Error, exceptions.NameError: global name 'AUTHENTICATED_USER' is not defined
