When DynamicRetry.fcc is used instead of the default login.fcc in the HTML forms authentication scheme then if user enters invalid credentials, the browser just shows the configured ServerErrorPage (SMERROR=00-0010) instead of the showing the DynamicRetry.unauth page with the info that the credentials are invalid.
Earlier, there was no check for whether SmFailure is due to invalid credentials or any other reason. As a result, error page set in ServerErrorFile ACO parameter was shown to user.
This issue has been fixed in Webagent version R12-SP2-CR-01 and 6.0-SP6.
Now the webagent correctly redirects to the .unauth file when DynamicRetry.fcc is used and incorrect credentials are entered.
