-------------------------------------
> Support SAML token signature without KeyInfo
> --------------------------------------------

> Key: FEDIZ-251
> URL: https://issues.apache.org/jira/browse/FEDIZ-251
> Project: CXF-Fediz
> Issue Type: Improvement
> Components: Plugin
> Affects Versions: 1.5.0
> Reporter: Arnaud MERGEY
> Assignee: Colm O hEigeartaigh
> Priority: Major
> Fix For: 1.5.1
>
>
> During a SAML authentication flow, Fediz is throwning NPE when
> signature is missing KeyInfo, which is supposed to be optional (if I
> understand saml spec correctly).
>
> While processing this kind of signature
