Hi, David!
Thank you for the help.

I'll try. Your authenticator is registered as a Plugin in a PAU in your
current site? I'm not sure the cause without more details, but when I
see this happen I've usually neglected one of the following:
What do you mean by "Your authenticator is registered as a Plugin in a
PAU in your current site"? I registered the authenticator as a utility
and assigned the utility name to the authenticatorPlugins attribute of
the PAU. Is it enough?
1. The credentials plugin is not selected and added.
2. The authenticator plugin is not selected and added.
I think the plugins were selected and added as well as the PAU. I could
access them with the queryUtility method later.
3. No permissions have been granted to the user, so even though the user
is valid, they don't have permissions to do anything and so another
authentication is being called as a backup. This is easy enough to
debug by putting print statements at strategic points in your plugin and
see if and when they show up in the Zope log.
Yes, I do debugging the same way. And the print statement at the first
line of the authenticator printed nothing. So I think the authenticator
wasn't called at all.
The PAU stuff has changed a lot over the history of Zope 3, so I've also
found it to happen when using outdated methods such as the ones in
Phillips first edition (which have since been updated to reflect the
latest methods - thanks Phillip).

Hello,
I try to create a plugin, which could authenticate users against an
external database. Here is the code:
from zope.component import provideUtility
from zope.app.authentication import PluggableAuthentication
from zope.app.authentication.interfaces import\
ICredentialsPlugin, IAuthenticatorPlugin
from zope.app.authentication.session import SessionCredentialsPlugin
from zope.app.security.interfaces import IAuthentication
from mypackage.Authentication import MyAuthenticatorPlugin
provideUtility(SessionCredentialsPlugin(), ICredentialsPlugin,\
'My Credentials Plugin')
provideUtility(MyAuthenticatorPlugin(), IAuthenticatorPlugin,
'My Authenticator Plugin')
pau=PluggableAuthentication('my_')
pau.credentialsPlugins=('Cascade Credentials Plugin', )
pau.authenticatorPlugins=('Cascade Authenticator Plugin', )
provideUtility(pau, IAuthentication, 'My Pluggable-Authentication
Utility'
This code is contained in the file mypackage/__init__.py, mypackage in
turn is loaded via ZCML. Both plugins and PAU are registered
successfully and I can access them with queryUtility. But the
authentication is carried through the standard mechanism and
MyAuthenticatorPlugin isn't even called.
Could any good soul help me with this case?
--Thanks,
Alexei
