I've tried to use the guide on http://aspn.activestate.com/ASPN/Mail/Message/zope-List/445507 to make an SQL-capable acl_users using LoginManager. Everything looks ok, but when I try to log in as a user in the database, I get the following error: Error Type: KeyError Error Value: _v_parent Traceback (innermost last): File /usr/lib/python2.1/site-packages/ZPublisher/Publish.py, line 162, in publish File /usr/lib/python2.1/site-packages/ZPublisher/BaseRequest.py, line 450, in traverse File /var/zope/Products/LoginManager/LoginManager.py, line 237, in validate (Object: acl_users) File /var/zope/Products/LoginManager/LoginMethods.py, line 147, in findLogin (Object: Basic Auth Login) File /var/zope/Products/LoginManager/LoginManager.py, line 194, in getItem (Object: acl_users) File /var/zope/Products/ZPatterns/Rack.py, line 59, in getItem (Object: UserSource) File /var/zope/Products/LoginManager/UserSources.py, line 517, in retrieveItem (Object: UserSource) File /var/zope/Products/ZPatterns/Rack.py, line 235, in _RawItem (Object: UserSource) File /usr/share/zope/lib/python/OFS/CopySupport.py, line 480, in _setId (Object: ) File /var/zope/Products/ZPatterns/DataSkins.py, line 254, in __set_attr__ (Object: ) File /var/zope/Products/ZPatterns/DataSkins.py, line 240, in _canonicalForm (Object: ) KeyError: _v_parent Using: LoginManager-0-8-8b1 ZPatterns-0-4-3p2 Zope Version (Zope 2.4.3 (source release, python 2.1, linux2), python 2.1.1, linux2) Python Version 2.1.1 (#1, Aug 13 2001, 19:37:40) [GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-96)] I've been trying to find good documentation about this for several days now. A HOWTO would be greatly appreciated!!! -- Robin
