cluster node attribute based authorization

2016-06-06 Thread Anand Kumar Sankaran 
All

I implemented a ClusterNode.userAttributes() based authorization mechanism.  I 
used a JWT Token to establish trust (passed via the userAttribute). This works 
fine.

The problem I have is that the JWT Token expires shortly after initial use.  
Now, if the node leaves the cluster and joins it again, the JWT Token in that 
node would be invalid.

How should I fix this?  Is there a callback I can implement when a node leaves 
a cluster that I can use to create a new JWT token and attach to it?

Any guidance would be appreciated.
