[Zope] Using the authenticate method on an authenticated user

[Asad Habib]

Hello. I am trying to use the authenticate method to
determine if a user is entering the same password as
the one they currently have. I have a form that allows
the user to change their password. So, after the user
authenticates(i.e. starts a Zope session), they
navigate to this form and type in their new password.
After the form is submitted but before changing the
user's password, I would like to check if the password
they are entering is different from the one they
currently have. If it is not, I redirect them to
another page informing them that they have to enter
another password. To check if the password the user
has entered matches their current password, I use the
following statement in a DTML method:

<dtml-if expr
"acl_users.getUser(name).authenticate(password,
REQUEST)">

However, using this statement gives me an error that
reads the following:

Error Type: Unauthorized
Error Value: The container has no security assertions.
Access to 'authenticate' of rwolf denied.

I have no idea why I am getting this error. Any help
would be greatly appreciated. Thanks.
