Since Login Manager isn't doing the trick, I've been trying User DB to authenticate to my postgresql DB. I get some strange errors, like when I try to view a page that is 'protected' by UserDb, I get the error message below. Also, when I click a user in the management screen, it says "the specified user does not exist". Arrggg this task is so simple but REALLY FRUSTRATING... Thank you, thank you, thank you... (to anyone who can help) Error Type: TypeError Error Value: argument 1: expected read-only character buffer, None found Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 162, in publish File /usr/local/zope/lib/python/ZPublisher/BaseRequest.py, line 440, in traverse File /usr/local/zope/lib/python/Products/UserDb/UserDb.py, line 310, in validate (Object: RoleManager) File /usr/local/zope/lib/python/AccessControl/User.py, line 437, in validate (Object: RoleManager) File /usr/local/zope/lib/python/Products/UserDb/UserDb.py, line 147, in getUsers (Object: RoleManager) File /usr/local/zope/lib/python/Products/UserDb/UserDb.py, line 52, in __init__ TypeError: (see above)
