You receive the following message when attempting to sign in to an eRaider-authenticated website.

Sorry, the web site you're trying to use is not authorized to take advantage of eRaider Web Sign-in.

Please return to your original site, or if you suspect fraudulent activity, contact your appropriate institution's Help Desk.

The website to which you are attempting to authenticate was not recognized by the legacy eRaider Web Sign-in (eRWS) service as being an authorized webapp.

Check with the developer of the website or with the department/college sponsoring the application. An error may have been made in the coding/development of the website such that it is not compliant with legacy eRWS standards. Ideally, the website administrator should use modern authentication methods, such as SAML (via Shibboleth).

Outcome

Once the source code of the website is corrected, you are able to sign in to the website successfully using your eRaider account.
