Hi,
I'm currently developing a xmpp client/server application with an Android app with the Asmack library as the client and a customized Openfire server (I added some protocol extensions). As the server will be public my question is, how can I restrict the access so only my custom client is capable to communicate with my customized public server. Is there any kind of auth mechanism like sending an global client auth token to the server?
Thanks for your help!
