Hi Adam,

I can see you are using pcs-0.9.x. In that case you should do:
pcs cluster auth srv1cr1 srv2cr1

In other words, use the first address of each node.
Authenticating all the other addresses should not cause any issues. It 
is pointless, though, as pcs only communicates via ring0 addresses.

Yes, that is correct.

X should be replaced by node names as seen by pacemaker. Once you set up 
and start your cluster, run 'pcs status' to get (amongs other info) the 
node names. In your configuration, they should be srv1cr1 and srv2cr1.
