grantm has asked for the wisdom of the Perl Monks concerning the following question:

I find myself in the uncomfortable position of having to communicate with an identity server using WS-Trust - a system for exchanging trusted security tokens built with SOAP + XML Digital Signatures.

No obvious WS-Trust framework/implementation leapt out at me from CPAN. When I search with Google for ws-trust +perl, Google suggests I retry my search without "perl" :-(

Anyone have any pointers to an existing Perl implementation?
