I'm not using anything like that, I access the zenoss instance directly on port 8080... my users are in LDAP directory if that does make a differnce.
I have tried the hints here: http://community.zenoss.org/thread/13381?start=15&tstart=0
But this doesn't really help me, I still just get "Anonymous" in the logfile... I have tried debugging in http_server.py and it seems as though I don't have the correct auth-cookie.
I tried to dump alle cookies (via pprint in http_server.py) and there are no __ginger_snap or alike that I can parse.
