We are setting up two siteminder nodes which are pointing to two different policy store but shared session store.
The configuration within policy store of both siteminder nodes are almost same , apart from certain host object and aco.
Now we can set up access gateway to create SMsession against each node , and the validation against the same node has no issue.
But the validation against the other node doesn't work.
The same setup to have different policy store but same session store works on our old production environment.
And it was design to provide HA and also keep the policy deployment separately.
