There is error in the existing documentation for VIP 9.1 install and config guide on Page 69 which has below:
Testing Self Service Portal IDP Proxy
1.Access the link <http://<dmzhost>:8080/dmzssp/DmzListener>
2.Enter your LDAP user name and password and click Submit.
3.If you want to provide Temporary security Codes to users, use the requestTempPasscode support in the SSP-IDP proxy in the following format: <http://<dmzhost>:8080/dmzssp/DmzListener>?requestTempPasscode=true
The url <http://<dmzhost>:8080/dmzssp/DmzListener> does not work, it will result in “forbidden” error 403. The correct url should be <http://<dmzhost>:8080/dmzssp> as described in the solution ID:SO18809 readme.txt.
