WIF : Is there a Java Equivalent?

Been asked this question a million times and now I have an answer of sorts.

If by WIF, you mean WS-Federation, then mosey on over to:

Apache CXF Fediz: An Open-Source Web Security Framework
 
This supports:

• WS-Federation 1.0/1.1/1.2
• SAML 1.1/2.0 Tokens
• Custom token support
• Publish WS-Federation Metadata document
• Role information encoded as AttributeStatement in SAML 1.1/2.0 tokens
• Claims information provided by FederationPrincipal interface

However, if by WIF by mean the FAM / SAM / CAM functionality then the jury is still out.

There is no direct Java replacement library for WIF.

Update:

Came across  auth10-java.

• This library speaks the WS-Federation protocol and SAML 1.1 and 2.0 tokens. It interops fine with Microsoft-related products like ADFS, Windows Azure Active Directory and Windows Identity Foundation. 

Update:

Also  OIOSAML.

Enjoy!
