Subscribing to a Resource in iCal

Question

I have been trying to figure out how to subscribe to the resources I have created on my OS-X server.
According to the documentation, this should be possible.
"A read-only delegate is another user who can see your calendar items, including free-busy times, but not change them. Sometimes this is called a “proxy user.”
This setting is useful for locations and resources. If you make a user or group a read- only delegate for the resource, the delegate can see the details of the resource’s use, rather than just whether the resource is busy."
You are supposed to be able to do this in iCal Server Utility, but I can't see anywhere to assign delegates.
Any help would be greatly appreciated.
tnx

according to Apple documents:
http://support.apple.com/kb/HT3897
To delegate read and write access of a resource to a group use the following command, where groupname is the name of the group and resourcename is the name of the resource:
sudo calendarservermanageprincipals --add-write-proxy groups:groupname resources:resourcename
To delegate read access of a resource to a group use the following command, where groupname is the name of the group and resourcename is the name of the resource:
sudo calendarservermanageprincipals --add-read-proxy groups:groupname resources:resourcename
To delegate read and write access of a resource to a group use the following command, where groupname is the name of the group and locationname is the name of the location:
sudo calendarservermanageprincipals --add-write-proxy groups:groupname locations:locationname
To delegate read access of a location to a group use the following command, where groupname is the name of the group and locationname is the name of the location:
sudo calendarservermanageprincipals --add-read-proxy groups:groupname locations:locationname
Once you have delegated access to resource or location, a client can view it in iCal via iCal > Preferences > Accounts > Delegation and selecting "Show" beside each resource and location.
