Authentication Updates

[ansoni]

Hello,
During internal productization, I added several feature to Ice. This is a commit of those changes:

• addition of "ice.use_blended" as a toggle between blended/unblended. Default behavior is blended.
• addition of a new route to redirect to the application context when someone hits '/'
• addition of an authentication framework. default is not enabled
• addition of a passphrase protected login plugin
• addition of a SAML login plugin
• updated README for these additions.

The first commit around services with '/' in the name was later removed with #100 being submitted in its place.

Lots of changes I know.

Thanks,

Anthony

This pull request looks good

Maybe this could be a pull request per feature to make it easier to digest?

Let me see if I can sort it out.

I'm excited to see the SAML plugin come with this enhancement!

[ansoni]

Glad to hear it. SAML was the whole reason for the login framework. It has the ability to limit what accounts are visible via the SAML assertion. This was a requirement for our internal usage.

Maintainers: Would it help if I annotated the sources? I'm not sure how to break this pull request into smaller chunks without re-branching and re-applying my code changes.

Closing this. I will re-work the pull request in the future.
