[Zope-CMF] Problem with LDAPUserFolder 1.1 and Zope2.5.1 final

[paolo]

I use de following configuration for a content management application:
Zope 2.5.1b1, CMF1.1, LDAPUserFolder 1.1, and all work fine.

I have a python script with proxy role set to Manager that make the call:
context.acl_users.getUser(user_id).getUserDN()

I upgraded to Zope2.5.1 final and the same script now trow an
Unauthorized exception on getUserDN() method that is protected by View
permission.

Error Type: Unauthorized
Error Value: You are not allowed to access getUserDN in this context
 
Traceback (innermost last):
