We recently implemented SAML with our Jenkins instance. If a user is not yet logged in via our corporate SSO and they click on a deep link (in an email for example) they get a "Not Found" which is confusing because it fails to say anything about not being logged in. What should happen is a redirect to the corporate SSO and then upon successful log in, the redirect back to the original deeply linked content.

I imagine that this will be an apache config thing.
Any advice to remedy this would be greatly appreciated.

My apache config is included.
