Hi Marvin, I have attached my config file, for which I have received comments from people from Citrix. Would that be ok if I just add this as an example config file? Feel free to comment on it as well, or to send me a corrected version, so that we have a good example shipped with the package... Thomas P.S: I'll upload a new version to SID only after the current one is migrated to Squeeze anyway.
