Get node subscription options error

I’m trying to get the node subscription options for a collection node whose pubsub#subscription_required value is set to 1.

First I try to subscribe, but the server replies with subscription-options required and a subid is neccessary.

Then I get the subid from querying my subscriptions and look it up and from the xml console of Vacuum-IM I send

 <subscribe-options xmlns="[http://jabber.org/protocol/pubsub](http://jabber.org/protocol/pubsub)"

node=‘node_1339853365824’ jid=“admin@server.local” subid=“XiAgD08D9R1TO64zLQ91U3ath12cCJX7wUQM6T56”/>

I get an error:

The user is not the owner of the node.

Thanks!
