[Zope] authenticated_user in Z SQL method not defined

[Christoph Landwehr]

Hi,

"SecurityGetUser()" was the hint I needed.
Thanx a lot!

Though I dont't know, why AUTHENTICATED_USER is not available in the 
context of an ZSQL-method since it is a method of
the Zope-defined web request variables:
"""AUTHENTICATED_USER
     An object that represents an authenticated user. When inserted into 
a DTML document, the value is the user name. This object currently 
provides no public attributes. Note that this variable may not be 
defined in Documents that are not protected by security information. """

)
which (I thought) is vailable in this context. Obviously I am wrong.

Regards Christoph
