XACML RBAC Implementations

[Fatih Turkmen <fturkmen@gmail.com>]

Hi,

I am looking for some standard RBAC implementations (e.g. API) that uses 
XACML (and its evaluation architecture) as the backend. 

Do you know any tool or library that is freely available or open to evaluation?

Thanks in advance.
