Open Stack

Hi All,

I have an application which does some HEAT transactions of creating
stack,polling for it and updating stack in a loop.

In my setup, /etc/keystone/keystone.conf has below settings:

expiration=3600

But my transaction loop takes more than 1 hr and AUTH token is expired in
between and I am getting :

 Exception in heat start task for stack
jsm-e08dceac-71fe-48e8-817e-93ec78881827
of network service e08dceac-71fe-48e8-817e-93ec78881827 due to

 ERROR: Authentication failed.Please try again with option
--include-password or export HEAT_INCLUDE_PASSWORD=1

Is there any means of making the auth-token not getting expired instead of
changing expiration time in keystone conf ??

Thanks

Eswar
