Steps to reproduce:
- Setup Kerberos authentication according to http://docs.alfresco.com/community/concepts/auth-kerberos-intro.html, and add it to the authentication chain, like so: authentication.chain=kerberos1:kerberos,alfrescoNtlm1:alfrescoNtlm
- Verify that you can login automatically to Share with Kerberos SSO using a browser configured to do so, such as an Internet Explorer browser running on a machine logged into the domain.
- Attempt to access Share using a browser which is not configured to use Kerberos, such as Chrome.
Expected behaviour: Share login form appears.
Actual behaviour: Share login page is loaded (/share/page?pt=login), but login form does not appear.
The expected behaviour works fine in Alfresco Community 5.0.c, so I would consider this a regression.
The same request to /share/service/messages_....js returns 200 OK (despite not being logged in) in an identically configured Alfresco 5.0.c.
