Unable to start daemon "open-xchange-groupware"

[ox_newbie]

Hi all,
I try to start this service open-xchange-groupware from root but cann´t and get this error:

/etc/init.d/open-xchange-groupware start
Starting Open-Xchange Groupware: start-stop-daemon: unrecognized option `--group'
Try `start-stop-daemon --help' for more information.

Can someone help me to fix that problem?

Thanks
Jimmy
