Symptoms

After configuring Windows Native Authentication (WNA) for SSO with short hostname, WNA login fails and the domain user is redirected to the SSO login page.

Entries in debug ssoServer.log:

...

SSOKerbeAuth.authenticate method ...
Tue May 15 12:21:58 CEST 2007 [DEBUG] AJPRequestHandler-ApplicationServerThread-7 Remote user name: {{UNAUTH_USER}}

Note: these symptoms may occur with WNA-enabled SSO for varying reasons. This Note is specific to environments where the following is true:
+ There are no SSO WNA initialization errors in the OC4J~OC4J_SECURITY~default_island~1 log with jazn debug enabled, nor errors when the client WNA login fails
+ The OC4J~OC4J_SECURITY~default_island~1 log with jazn debug enabled shows that SSO requests a ticket on startup for the correct HTTP principal
+ SSO is configured for access using the short hostname, not the Fully-Qualified Domain Name (FQDN) 
+ the client IE browser is correctly configured to trust the SSO site
+ the client machine is logged into the correct Windows domain
