identify, authentication, authorization

[dinesh pande]

Most of the specs talk abou the same identify, authentication, authorization stuff..

I am a bit confused on how I should relate these to the specs.

Is it possible for someone to write a one punch liner about each spec and what they exactly do.

I still can't get what this Libery Project is about and how it is different from SSL, Digital Cert, SAML , XACML, WS-Security

Thanks
