I i access uri on jenkins beyond vase url, eg https://bhaus.gruppe.de/jenkins/job/MyJOB/ i get HTTP 404 .
I i call https://bhaus.gruppe.de/jenkins/ and authenficate with user /pwd ( in my case project matrix against ldap realm) and the call https://bhaus.gruppe.de/jenkins/job/MyJOB/ it works!
My esceptation would be that if not authenficated the user get redirected to login mask and the redirectd to entered url after successfull authefication.
I think its a War file web,xm. configuration issue.
