Need help: SAML Implementation

Hello, 

 
I am a graduate student pursuing 
Masters in Information Networking by Carnegie Mellon University (at AIT Campus - 
Greece) and I am writing to seek your help with my graduate project in the area 
of "XML Security" (SAML in particular). 

Here's my problem: 

For some 
time I am searching the Net with hope to find some tools which implement SAML. I 
found discussions about JSAML and Sun One Identity Server but this tools are no 
longer available. 

 
I will be very grateful if you can 
help me get these or other similar tools, and provide any other 
material/guidance related to this topic. 
 
Thank you in 
advance,
