The EXCLUDEALL_ROAM line prevents usage of roaming by a particular user, host, group, host_group, IP address, or project. If you specify group, host_group, or internet_group, it must be defined by a GROUP or HOST_GROUP or INTERNET_GROUP line in the options file. Anyone on the EXCLUDEALL_ROAM list is not allowed to set up roaming licenses.
