Unable to access mod_osso protected application on the mid-tier with single-server architecture.

The SSO login page is displayed, but after valid credentials are entered and submitted, the following error occurs:

   Oracle SSO Failure - Unable to process request
   Either the requested URL was not specified in terms of a fully-qualified hostname or OHS single sign-on is incorrectly configured.
   Please notify your administrator.

OIDDAS login is successful, the problem only occurs when accessing mid-tier mod_osso protected applications.

The error does not occur when using Mozilla-based browsers, only occurs with Internet Explorer.

SSO debug log (ssoServer.log) shows that SSO login was successful.

Entry in mid-tier HTTP Server error_log with debug LogLevel:

[OSSO] W05:
Requested URL is not specified in terms of fully-qualified host name or invalid SSO partner configuration. Host from request <hostname>:<port>, registered host <hostname>:<port>

The request port and the registered port in the log message are different, but the hostname is the same.
