is there any possibility to control, authenticate members joining to a group?
i saw something in the jgroups documentation about encryption but if i understood right it's about encrypting the communication and not about authentication of the members of a group.
is there any alternative solution to make sure only defined members can take part of the multicast communication?
thanks for your help in advance!
No, there isn't. If you google for this, there was a discussion of it afair ca 2 months ago, and I suggested a protocol just below GMS
