We have successfully integrated our 18.104.22.168 instance with 10giAS SSO with AD and WNA. Everything is working fine, but we have some issues. One of them was unable to modify or delete Partner Application. Even with orcladmin user we are not able to Administer Partner Applications. We are working with Oracle to get this resolved, but found one workaround to modify them from backend. We can found them in table "WWSSO_PAPP_CONFIGURATION_INFO$" under orasso user. You can update this table as workaround. Till I get some solution to share.
Happy Troubleshooting !!!
