The parameters look correct as far as I can tell (comparing with
http://fss.plone.uni-giessen.de/fss/...upplicant.conf).
One line looks suspicious though: anonymous_identity="anonymous@uni-giessen.de"
I'm not sure if it should contain the "=" sign. Try running the script from the command line (see my second or third post) and check the output, and possibly remove the = and check again.
Good luck
