[Zope] z3c.authenticator conflicts with zope.app.security

[Dr. Volker Jaenisch]

Hi Zope People!

I got this conflict (see below) error utilizing z3c.authenticator in 
bluebream.

Learned from
http://www.mail-archive.com/zope3-users@zope.org/msg08290.html
that
"""
 > Both registrations won't work at the same time.
 > You need to get rid of one based on what sort of authentication you're
 > using.
"""

This is out of question. The question is how to do this. There is no direct
dependecy on zope.app.security in my zcml code.

Any help apreciated, thanks in advance

Volker

Any help appreciated.
Thanks in advance
