Information in this document applies to any platform.
Oracle Access Manager (OAM) 11g SSO login using an OSSO Agent is failing after Global Inactivity Timeout (GITO) is configured.
When a mod_osso protected resource is accessed, the user is redirected to the OAM SSO login page as expected.
However when the user submits valid credentials, the login page is re-displayed with blank username and password fields.
The HTTP header trace shows that the OAM_ID (OAM SSO cookie) , OHS-ID (mod_osso cookie) and OSSO_USER_CXT (GITO cookie) are set during after the credentials are submitted. But the login page is then re-displayed.
In the Oracle HTTP Server (OHS) log the following warning is written:
Steps to reproduce
1. Access the mod_osso protected resource in the browser.
2. The OAM SSO login page is displayed.
3. Submit valid credentials.
4. The OSSO login page is re-displayed with blank username and password fields.
