Subject RE: REST security enhancements
Date Thu, 06 Feb 2014 09:06:58 GMT
Hi Sergei,

For me is also interesting to have a simple way to configure REST service with authentication
schemas it accepts.
For example one service will accept only SAML, second service accepts either Basic Auths or
SAML, depending what client sent.
For SOAP services that is quite easy to do using WS-Policy assertions.
Do you think kind of similar mechanism is useful for REST?

Regards,
Andrei.
