[Zope-dev] LoginManager error

[Bertrand CROQ]

Hi,
  I am using Zope 2.3.0 with ZPatterns 0.4.3b2 and LoginManager 0.8.8b1. =
When=20
I try to use LoginManager (following the tutorial about LoginManager and=20
SQL), here is the error I get in the browser:

Type: TypeError
Value: not enough arguments; expected 3, got 2

Traceback (innermost last):

I don't know a lot about Zope/Python (I work on it since 2 weeks) so I do=
n't=20
know if this is an install error, a development error (I mean, did I do=20
something wrong when using LoginManager, surely!!), or an error in=20
LoginManager; is this a known error?

The error seams to be in LoginMethods.py:149 as it calls user.authenticat=
e()=20
with two parameters where LoginUser's authenticate() takes 3=20
parameters; but, once again, I might be missing something as I am a=20
beginner...

Thanks
