Hi Kamran,
I couldn't find a document that has step-by-step procedure on setting up ACS/safeword token server. However, please go through the below listed link. This would explain ACS side configuration. On the Safeword
Token server user database
http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/user/guide/UsrDb.html#wp356090
On the safeword token server, you should have ACS as a host client configured.
Please let us know if you face any issues while doing integration.
