[Zope-dev] LoginManager and ZPatterns

I've been fiddling a bit with the LoginManager; but can't seem to make it work. The product versions are ZPatterns 0.3.0 and LoginManager 0.8.6. (Downgraded the ZPatterns product because the LoginManager couldn't find a class named .. SheetProviderContainer, I think). When adding a LoginManager object, it raises a TypeError exception, on line 313 in PlugIns.py, saying that a keyword parameter was redefined. I've also been looking around for some useful documentation and searched the mailing-lists.. Anyone had success with these two products, and would care to share a howto? Thanks in advance. -Morten
