Now I've got round this by calling rls_handle_subscribe($tu), if $tu is detected as a group uri. So $tu will be used as watcher_username to compare with the RL's user. Seems to work but not sure if this is the right way, i.e. is there a way of putting the group's RL under a special URL so that every other user can get its RL document?

Is there a way of allowing user1 and user2 to both subscribe to a common group of contacts, group.common? Seems that each user can only subscribe to its own resource list and won't be able to subscribe to other user's resource list. For example, both user1 and user2's RLS services documents contain resource-list pointing to group1's resource list, like this: <?xml version='1.0' encoding='UTF-8'?> <rls-services xmlns:rl="urn:ietf:params:xml:ns:resource-lists" xmlns="urn:ietf:params:xml:ns:rls-services"> <service uri='sip:group1@mydomain.com'> <resource-list>http://mydomain.com:5060/xcap-root/resource-lists/users/group1/generallist.xml/~~/resource-lists/list%5b@name=%22group-auto%22%5d </resource-list> <packages> <package>presence</package> </packages> </service> ... ... </rls-services> The problem is the watcher_user in this case would be user1 or user2, which is not 'group1' so the resource list document fails to be retrieved. How can I allow user1 and user2 to retrieve group1's RL document? Thank you!
