Symptoms

Unable to login to OIDDAS with previously working configuration.

When the Login link is clicked the SSO login page is displayed with the following error, before entering any credentials:

    Error: WWC-41400 Unexpected Errors


The URL displayed in the browser is http(s)://<hostname.domain>:<port>/pls/orasso/orasso.wwsso_app_admin.ls_login, not http(s)://<hostname.domain>:<port>/sso/auth as expected.

The error occurs for both HTTP and HTTPS site access with two different osso.conf files. Valid Partner Applications for these protocols, hostnames and ports exist in the SSO repository. The osso.conf files have been de-obfuscated with utility ssomigrate and contents verified correct.

HTTP Header trace shows HTTP-404 error occurring for the call to ls_login.

HTTP Server <virtualhost> configuration includes RewriteEngine On and RewriteOptions Inherit.

After enabling SSO debug logging in the <infra_home>/sso/conf/policy.properties file, subsequent review of the log file <infra_home>/sso/log/ssoServer.log when the Login link is clicked reveals no new entries are entered.

Enabling SSO PL/SQL debug logging as described in <Note:198732.1> 'How to Set up SSO Debugging' shows a user-defined exception in get_url_on_cancel, e.g.,

LOG_DATE 	SUBSTR(USESSION_ID,1,15) 	MSG
--------------- ------------------------ 	--------------------------------------------------
07-OCT-05	001200190001			entry: get_sso_cookie_namespace
07-OCT-05	001200190001			entry: utf8_to_db_charset
07-OCT-05	001200190001			Error in get_url_on_cancel: User-Defined Exception
07-OCT-05	001200190001			setting DAD mode to : sso

The SSO and SSO Repository database servers can successfully ping the hostname specified in the browser and it resolves to the correct IP address.
